The liquid crystal display device includes a liquid crystal panel, a cover bottom, a rear cover, and a guide panel. The liquid crystal panel displays an image. The cover bottom accommodates a light source configured to provide light to the liquid crystal panel. The rear cover accommodates the cover bottom. The guide panel is positioned on the cover bottom to support the liquid crystal panel. Each of the guide panel and the cover bottom includes a hook which protrudes from a surface so as to be fitted to a latching portion of the rear cover. ## Claims ### Claim 1 A liquid crystal display device comprising: a liquid crystal panel configured to display an image; a cover bottom accommodating a light source configured to provide light to the liquid crystal panel, the cover bottom having a bottom side wall; a rear cover accommodating the cover bottom, the rear cover having a cover side wall; and a guide panel on the cover bottom to support the liquid crystal panel, the cover side wall of the rear cover disposed between the guide panel and the bottom side wall of the cover bottom, wherein the guide panel and the cover bottom include hooks that protrude from respective surfaces of the guide panel and the cover bottom, the hooks being fitted into corresponding latching portions of the cover side wall of the rear cover to couple the guide panel and the cover bottom to the rear cover. ### Claim 2 (depends on 1) The liquid crystal display device of claim 1, wherein the guide panel comprises a first hook to be inserted into a first latching portion of the rear cover, and the cover bottom comprises a second hook to be inserted into a second latching portion of the rear cover. ### Claim 3 (depends on 2) The liquid crystal display device of claim 2, wherein each of the first hook and the second hook has an inclined surface facing a cover base of the rear cover. ### Claim 4 (depends on 2) The liquid crystal display device of claim 2, wherein the first hook protrudes from a panel side wall of the guide panel, and includes a protruding portion that protrudes laterally inward from the panel side wall, and an inclined portion which protrudes inwardly at an incline from the panel side wall. ### Claim 5 (depends on 4) The liquid crystal display device of claim 4, wherein the rear cover comprises a cover base supporting a bottom base of the cover bottom, and the cover side wall covers the bottom side wall of the cover bottom, and wherein an upper part of the cover side wall has an outer side wall with an inclined edge to correspond to a position of the first hook. ### Claim 6 (depends on 2) The liquid crystal display device of claim 2, wherein the second hook protrudes from the bottom side wall of the cover bottom, and includes a protruding portion which protrudes laterally outward from the bottom side wall, and an inclined portion which protrudes outwardly at an incline from the bottom side wall. ### Claim 7 (depends on 6) The liquid crystal display device of claim 6, wherein the rear cover comprises a cover base supporting a bottom base of the cover bottom, and the cover side wall covers the bottom side wall of the cover bottom, and wherein an upper part of the cover side wall has an inner side wall with an inclined edge to correspond to a position of the second hook. ### Claim 8 (depends on 7) The liquid crystal display device of claim 7, wherein the cover bottom comprises a third hook to be inserted into a third latching portion of the rear cover. ### Claim 9 (depends on 8) The liquid crystal display device of claim 8, wherein the third hook protrudes from a bottom side wall of the cover bottom, and includes a protruding portion which protrudes laterally outward from the bottom side wall, and an inclined portion which protrudes outwardly at an incline from the bottom side wall, the protruding portion being between the cover base and the inclined portion. ### Claim 10 (depends on 9) The liquid crystal display device of claim 9, wherein the inclined portion of the third hook faces a panel support of the guide panel. ### Claim 11 A liquid crystal display device comprising: a liquid crystal panel configured to display an image; a cover bottom accommodating a light source configured to provide light to the liquid crystal panel; a guide panel on the cover bottom to support the liquid crystal panel; and a rear cover accommodating the cover bottom, wherein the cover bottom comprises a cover bottom hook which protrudes from a surface of the cover bottom and is fitted to an adjacent latching portion of one of the rear cover or the guide panel, and wherein the cover bottom hook protrudes from a bottom side wall of the cover bottom, and includes a protruding portion which protrudes laterally outward from the bottom side wall, and an inclined portion which protrudes outwardly at an incline from the bottom side wall, and wherein the inclined portion of the cover bottom hook faces a cover base of the rear cover. ### Claim 12 (depends on 11) The liquid crystal display device of claim 11, wherein the guide panel includes a hook latching portion into which the cover bottom hook is inserted. ### Claim 13 (depends on 12) The liquid crystal display device of claim 12, wherein the rear cover includes a rear cover hook that protrudes from a cover side wall of the rear cover, and the rear cover hook is inserted in the hook latching portion of the guide panel. ### Claim 14 (depends on 13) The liquid crystal display device of claim 13 wherein the cover bottom hook protrudes outwardly from the bottom side wall of the cover bottom toward the cover side wall of the rear cover, and the rear cover hook protrudes inwardly from the cover side wall of the rear cover toward the bottom side wall of the cover bottom. ### Claim 15 (depends on 14) The liquid crystal display device of claim 14 wherein the cover bottom hook is positioned between the cover base of the rear cover and the rear cover hook. ### Claim 16 (depends on 13) The liquid crystal display device of claim 13, wherein the rear cover hook includes a protruding portion which protrudes laterally inward from the cover side wall, and an inclined portion which protrudes inwardly at an incline from the cover side wall, and wherein the inclined portion of the rear cover hook faces a panel support of the guide panel. ### Claim 17 (depends on 16) The liquid crystal display device of claim 16, wherein the cover bottom hook and the rear cover hook are inserted into the hook latching portion to be coupled to each other. ### Claim 18 (depends on 11) The liquid crystal display device of claim 11, wherein the rear cover includes cover side wall having a hook latching portion into which the cover bottom hook is inserted, and the guide panel includes a panel side wall covering an outer side of the cover side wall of the rear cover. ### Claim 19 (depends on 18) The liquid crystal display device of claim 18, wherein the panel side wall of the guide panel includes a guide panel hook which protrudes inwardly from a side surface of the panel side wall and is inserted into a second hook latching portion of the cover side wall of the rear cover. ### Claim 20 A liquid crystal display device comprising: a liquid crystal panel configured to display an image; a cover bottom accommodating a light source configured to provide light to the liquid crystal panel; a rear cover accommodating the cover bottom; and a guide panel on the cover bottom to support the liquid crystal panel, wherein the guide panel and the cover bottom include hooks that protrude from respective surfaces of the guide panel and the cover bottom, the hooks being fitted into corresponding latching portions of the rear cover to couple the guide panel and the cover bottom to the rear cover, wherein the guide panel comprises a first hook to be inserted into a first latching portion of the rear cover, and the cover bottom comprises a second hook to be inserted into a second latching portion of the rear cover, and wherein the second hook protrudes from a bottom side wall of the cover bottom, and includes a protruding portion which protrudes laterally outward from the bottom side wall, and an inclined portion which protrudes outwardly at an incline from the bottom side wall.
