The frame supports the display panel. The frame has a first protruding portion that contacts with an area of a rear facing surface of the optical member within a predetermined distance from a center portion of the optical member. The first protruding portion has an overall rectangular shape with a step part at at least one corner of the overall rectangular shape. ## Claims ### Claim 1 A display device comprising: a light source; an optical member; a display panel; a frame that supports the display panel, the frame having a first protruding portion and a peripheral portion, the first protruding portion protruding forward relative to the peripheral portion and contacting with an area of a back surface of the optical member within a predetermined distance from a center portion of the optical member; and a cover member that covers at least the first protruding portion from a rear of the display device, the first protruding portion having an overall rectangular shape with at least one corner removed as viewed in a direction perpendicular to the back surface of the optical member, and the frame further having a projection that projects rearward relative to the first protruding portion at a location of the at least one corner removed and supports a member of the display device at a rear of the frame. ### Claim 2 (depends on 1) The display device according to claim 1, further comprising a heat sink to which the light source is attached, the heat sink having a second protruding portion that contacts with the optical member, and a third protruding portion that is disposed closer to the first protruding portion than the second protruding portion and contacts with the optical member. ### Claim 3 (depends on 2) The display device according to claim 2, wherein the light source includes a plurality of light sources that is arranged along a first direction that is parallel to a display surface of the display panel, the second protruding portion and the third protruding portion extend in the first direction, respectively. ### Claim 4 (depends on 3) The display device according to claim 3, wherein the second protruding portion and the third protruding portion overlap with respect to each other as viewed in a second direction that is parallel to the display surface and is perpendicular to the first direction. ### Claim 5 (depends on 1) The display device according to claim 1, wherein the display panel has a rectangular shape, and end edges of the first protruding portion in a longitudinal direction of the display panel linearly extend along a transverse direction of the display panel, respectively. ### Claim 6 (depends on 5) The display device according to claim 5, wherein the first protruding portion has an end portion that has a width smaller than a width of the first protruding portion between the end edges of the first protruding portion, and that protrudes in the transverse direction. ### Claim 7 (depends on 6) The display device according to claim 6, wherein the end portion of the first protruding portion has a concave edge near a center of the end portion in the longitudinal direction that is concaved in the transverse direction, and the concave edge is aligned with a center of the frame in the transverse direction. ### Claim 8 (depends on 1) The display device according to claim 1, wherein the first protruding portion has a curved corner edge as viewed in a direction perpendicular to a display surface of the display panel. ### Claim 9 (depends on 2) The display device according claim 2, wherein the second protruding portion and the third protruding portion extend in a first direction that is parallel to a display surface of the display panel, respectively, and are at least partially spaced apart from each other in a second direction that is parallel to the display surface and is perpendicular to the first direction. ### Claim 10 (depends on 9) The display device according to claim 9, wherein the first protruding portion and the third protruding portion are spaced part from each other in the second direction. ### Claim 11 (depends on 9) The display device according to claim 9, wherein the heat sink and the first protruding portion are spaced part from each other in the second direction. ### Claim 12 (depends on 2) The display device according to claim 2, wherein the first protruding portion bulges towards the optical member relative to a base portion of the frame, and the second protruding portion and the third protruding portion bulge towards the optical member relative to a base portion of the heat sink, respectively. ### Claim 13 (depends on 12) The display device according to claim 12, wherein an amount by which the first protruding portion bulges towards the optical member relative to the base portion of the frame is larger than an amount by which the second protruding portion and the third protruding portion bulge towards the optical member relative to the base portion of the heat sink. ### Claim 14 (depends on 13) The display device according to claim 13, wherein the frame further has an intermediate portion that bulges towards the optical member relative to the base portion of the frame by an amount that is smaller than the amount by which the first protruding portion bulges towards the optical member relative to the base portion of the frame. ### Claim 15 (depends on 14) The display device according to claim 14, wherein the intermediate portion is located outward relative to the first protruding portion in a first direction in which the second and third protruding portion extend, and extends in a second direction that is parallel to the display surface and is perpendicular to the first direction. ### Claim 16 (depends on 14) The display device according to claim 14, wherein the intermediate portion extends in a first direction in which the second and third protruding portion extend, and is located outward relative to the first protruding portion in a second direction that is parallel to the display surface and is perpendicular to the first direction, and the first protruding portion is disposed between the third protruding portion and the intermediate portion in the second direction. ### Claim 17 (depends on 5) The display device according to claim 5, wherein the first protruding portion has a dimension in the transverse direction that is larger than half of an entire dimension of the frame in the transverse direction. ### Claim 18 (depends on 6) The display device according to claim 6, wherein the step part is defined between a large dimension part of the end portion and a small dimension part of the end portion that has a smaller dimension than that of the large dimension part in the longitudinal direction and extends in the transverse direction relative to the large dimension part. ### Claim 19 (depends on 2) The display device according to claim 2, wherein the heat sink is independently formed as a separate member from the frame. ### Claim 20 (depends on 1) The display device according to claim 1, wherein the display panel has a rectangular shape, and the first protruding portion has a larger dimension in a longitudinal direction of the display panel than in a transverse direction of the display panel.
