Display device
View Patent ↗A display device includes a display panel, a light source that emits light, a light guide plate comprising a lateral surface that receives the light, wherein the light source emits the light to the lateral surface from a main surface to a back surface of the display panel, a supporting member provided between a peripheral portion of the display panel and a peripheral portion of the light guide plate and that supports the peripheral portion of the display panel, a reflective sheet disposed so as to cover a back surface on an opposite side of the main surface of the light guide plate and that comprises an opening at a position corresponding to the peripheral portion of the light guide plate, and a back surface enclosure disposed so as to oppose the reflective sheet and that includes a first fixing part and a second fixing part.
1. A display device, comprising:
a display panel;
a light source that emits light;
a light guide plate comprising a lateral surface that receives the light, wherein the light source emits the light to the lateral surface from a main surface to a back surface of the display panel;
a reflective sheet that covers a back surface on an opposite side of the main surface of the light guide plate and that comprises an opening at a position corresponding to a peripheral portion of the light guide plate;
a back surface enclosure formed of resin;
a supporting member provided between a peripheral portion of the display panel and a peripheral portion of the light guide plate and that supports the peripheral portion of the display panel; and
a screw that mutually fastens the supporting member and the back surface enclosure,
wherein the back surface enclosure opposes the reflective sheet and comprises:
a first fixing part that contacts a back surface of the light guide plate through the opening of the reflective sheet; and
a second fixing part that contacts a surface of the reflective sheet,
wherein a difference between a height of the first fixing part from an inner surface of the back surface enclosure to the back surface of the light guide plate and a height of the second fixing part from the inner surface is larger than a thickness of the reflective sheet,
wherein a first portion of the back surface of the light guide plate facing the first fixing part and a second portion of the back surface of the light guide plate facing the second fixing part are co-planar, and
wherein the first fixing part and the opening of the reflective sheet are respectively disposed to correspond with a placement location of the screw.
2. The display device according to claim 1 , wherein
a height of the first fixing part from the back surface enclosure is higher than a height of the second fixing part from the back surface enclosure.
3. The display device according to claim 1 , wherein
the first fixing part and the second fixing part extend continuously along a peripheral portion of the light guide plate.
4. The display device according to claim 1 , wherein
the first fixing part and the second fixing part are disposed discontinuously along the peripheral portion of the light guide plate.
5. The display device according to claim 1 , wherein
the back surface enclosure, the first fixing part, and the second fixing part are integrally molded from resin.
6. The display device according to claim 2 , wherein
the first fixing part and the second fixing part extend continuously along a peripheral portion of the light guide plate.
7. The display device according to claim 2 , wherein
the first fixing part and the second fixing part are disposed discontinuously along the peripheral portion of the light guide plate.
8. The display device according to claim 2 , wherein
the back surface enclosure, the first fixing part, and the second fixing part are integrally molded from resin.
9. The display device according to claim 3 , wherein
the back surface enclosure, the first fixing part, and the second fixing part are integrally molded from resin.
10. The display device according to claim 4 , wherein
the back surface enclosure, the first fixing part, and the second fixing part are integrally molded from resin.
11. The display device according to claim 1 , wherein
the opening is one of a plurality of openings,
the first fixing part is one of a plurality of first fixing parts,
the second fixing part is one of a plurality of second fixing parts, and
the plurality of first fixing parts and the plurality of second fixing parts are alternately disposed.
12. The display device according to claim 1 , wherein
the opening, the first fixing part, and the second fixing part are disposed at a position different from a position around the lateral surface.
13. The display device according to claim 1 ,
wherein
the peripheral portion of the light guide plate exposed through the opening of the reflective sheet is interposed between the first fixing part and the supporting member, and
the peripheral portion of the light guide plate covered by the reflective sheet is interposed between the second fixing part and the supporting member.
