The display device includes a liquid crystal panel including an active area where an image is output and a bezel area positioned around the active area, a backlight unit for emitting light to a rear surface of the liquid crystal panel, a panel guide including a seating portion where an edge of the rear surface of the liquid crystal panel is seated, and a sidewall portion for covering a side surface of the liquid crystal panel, a bonding member provided in the bezel area to bond the edge of the rear surface of the liquid crystal panel to the seating portion, and a lower polarizing member constituting the rear surface of the liquid crystal panel and having an edge overlapping a part of a front surface of the bonding member. ## Claims ### Claim 1 A display device comprising: a liquid crystal panel comprising an active area in which an image is output and a bezel area positioned around the active area; a backlight unit configured to emit light to a rear surface of the liquid crystal panel; a panel guide comprising a seating portion allowing an edge of the rear surface of the liquid crystal panel to be seated thereon, and a sidewall portion configured to cover a side surface of the liquid crystal panel; a bonding member provided in the bezel area and configured to bond the edge of the rear surface of the liquid crystal panel to the seating portion; and a lower polarizing member constituting the rear surface of the liquid crystal panel and having an edge overlapping a part of a front surface of the bonding member, wherein the liquid crystal panel is formed by bonding an upper substrate and a lower substrate facing each other to each other, the lower polarizing member being arranged on a rear surface of the lower substrate, wherein the bonding member is provided in the bezel area, and wherein a width by which the bonding member contacts the lower substrate is greater than or equal to two-thirds of a width of the bezel area, and a width by which the bonding member overlaps the lower polarizing member is greater than or equal to half a width by which the lower polarizing member and the bezel area overlaps each other. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the liquid crystal panel comprises: an area colored in black to block incident light from the backlight unit and absorb light emitted through the side surface along the liquid crystal panel, the area being provided at the edge of the rear surface of the liquid crystal panel corresponding to the bezel area. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the panel guide comprises: a groove provided in a surface of the sidewall portion facing the side surface of the liquid crystal panel; and a matt tape provided in the groove to absorb light emitted through the side surface of the liquid crystal panel. ### Claim 4 (depends on 1) The display device according to claim 1, wherein the side surface of the liquid crystal panel is coated with a sealing member to block light emitted through the side surface of the liquid crystal panel. ### Claim 5 (depends on 4) The display device according to claim 4, wherein the sealing member overflows toward the rear surface of the liquid crystal panel to seal a side surface of the lower substrate or covers the side surface of the liquid crystal panel and a side surface of the bonding member together. ### Claim 6 (depends on 1) The display device according to claim 1, wherein the liquid crystal panel further comprises: an upper polarizing member on a front surface of the display device, and wherein the upper polarizing member covers the side surface of the liquid crystal panel. ### Claim 7 (depends on 1) The display device according to claim 1, wherein the liquid crystal panel comprises: a diffused reflection pattern on at least one of the side surface and the edge of the rear surface. ### Claim 8 (depends on 7) The display device according to claim 7, wherein the diffused reflection pattern is at least one of an embossed or engraved dot pattern, a serration pattern, and a pyramid pattern. ### Claim 9 (depends on 1) The display device according to claim 1, wherein the bonding member is a conductive foam pad, and is connected to a metal member included in the display device via a conductive tape. ### Claim 10 (depends on 9) The display device according to claim 9, wherein the metal member is a rear cover configured to define an outer appearance of a rear surface of the display device. ### Claim 11 (depends on 1) The display device according to claim 1, wherein the bezel area has a width of 3 to 6 mm.
