The light source emits light. The display panel displays image. The optical sheet laminate transmits the light directed to the display panel. The cabinet forms a housing of the display device, the cabinet having a front cabinet and a rear cabinet. The frame holds the optical sheet laminate, the frame having a front frame and a rear frame. The optical sheet laminate includes a first optical sheet having an opening near an edge of the first optical sheet, and at least one second optical sheet at least partially contacting with the first optical sheet and having an opening near an edge of the at least one second optical sheet. The front frame and the rear frame are attached to the front cabinet with a screw. ## Claims ### Claim 1 A display device comprising: a light source that emits light; a display panel that displays image; and an optical sheet laminate that transmits the light directed to the display panel; a cabinet forming a housing of the display device, the cabinet having a front cabinet and a rear cabinet, the front cabinet and the rear cabinet being made from a resin material; a frame holding the optical sheet laminate, the frame having a front frame and a rear frame; and a reflective sheet attached to the rear frame, the optical sheet laminate including a first optical sheet having an opening edge defining an opening near an edge of the first optical sheet, and at least one second optical sheet at least partially contacting with the first optical sheet and having an opening edge defining an opening near an edge of the at least one second optical sheet, the opening edge of the first optical sheet and the opening edge of the at least one second optical sheet overlapping with the reflective sheet as viewed from a front elevational view of the display device, respectively, the front frame and the rear frame being attached to the front cabinet with a screw at a location near a bottom edge of the display panel, and the rear cabinet covering the rear frame from a rear of the rear frame such that the rear frame does not expose rearward. ### Claim 2 (depends on 1) The display device according to claim 1, further comprising a diffusing plate that diffuses the light emitted from the light source, the at least one second optical sheet and the first optical sheet being disposed on the diffusing plate in this order. ### Claim 3 (depends on 1) The display device according to claim 1, further comprising a latching component inserted into the opening of the at least one second optical sheet. ### Claim 4 (depends on 3) The display device according to claim 3, wherein the opening of the at least one second optical sheet has a width that is less than a length of the latching component. ### Claim 5 (depends on 1) The display device according to claim 1, further comprising a latching component inserted into the opening of the first optical sheet. ### Claim 6 (depends on 3) The display device according to claim 3, wherein the opening of the at least one second optical sheet has a width that is less than a length of the latching component. ### Claim 7 (depends on 1) The display device according to claim 1, wherein the first optical sheet has a plurality of the openings on a plurality of the edges of the first optical sheet, and the at least one second optical sheet has a plurality of the openings on a plurality of the edges of the at least one second optical sheet. ### Claim 8 (depends on 1) The display device according to claim 1, wherein the front frame and the rear frame are attached to a rib of the front cabinet with the screw. ### Claim 9 (depends on 1) The display device according to claim 1, wherein the rear frame is attached to the rear cabinet with a screw. ### Claim 10 (depends on 1) The display device according to claim 1, wherein the front frame surrounds peripheral edges of the optical sheet laminate, and the rear frame houses the light source. ### Claim 11 (depends on 1) The display device according to claim 1, wherein the front cabinet covers the rear cabinet to surround side peripheral edges of the display panel. ### Claim 12 (depends on 1) The display device according to claim 1, wherein the front frame is made from a resin material. ### Claim 13 (depends on 1) The display device according to claim 1, wherein the rear frame is made from a metal material. ### Claim 14 (depends on 1) The display device according to claim 1, wherein the opening of the first optical sheet and the opening of the at least one second optical sheet are at least partially aligned with each other. ### Claim 15 (depends on 1) The display device according to claim 1, wherein the rear frame has an outer peripheral portion with a flat component that extends outward relative to a center of the display device and a bent part that extends rearward from an outer edge of the flat component, and the front frame and the front cabinet are fastened to the bent part of the rear frame with the screw. ### Claim 16 (depends on 15) The display device according to claim 15, wherein the front cabinet has a front part and an extending part that rearwardly extends from the front part, and the front frame has a side wall that is disposed between the bent part of the rear frame and the extending part of the front cabinet. ### Claim 17 (depends on 16) The display device according to claim 16, wherein the rear cabinet has a side wall, and the side wall of the front frame and the extending part of the front cabinet are disposed between the bent part of the rear frame and the side wall of the rear cabinet. ### Claim 18 (depends on 15) The display device according to claim 15, wherein the rear frame is attached to the rear cabinet with a screw at a location inward of the outer peripheral portion of the rear frame relative to the center of the display device.
