Abstract

A display assembly used for a display device includes a substrate, a protective member, and a first polarizing plate. The protective member is configured to protect the substrate. The first polarizing plate is disposed between the substrate and the protective member and configured to add a polarizing effect. The first polarizing plate has a first through hole through which light passes toward a back side of the display assembly. At least one of the substrate and the protective member includes a protruding portion having light transmissivity and protruding toward the first through hole.

Claims (62)

1. A display assembly to be used for a display device, the display assembly comprising:

a substrate;

a protective member configured to protect the substrate; and

a first polarizing plate disposed between the substrate and the protective member and configured to add a polarizing effect, wherein

the first polarizing plate has a first through hole through which light passes toward a back side of the display assembly,

at least one of the substrate and the protective member includes a base portion having a flat plate shape and a protruding portion having light transmissivity and protruding from the base portion toward the first through hole,

the protruding portion includes a first surface opposed to a first wall of the first through hole and a second surface opposed to a second wall of the first through hole,

the first surface is separated from the first wall with a first space between the first surface and the first wall, and

the second surface is separated from the second wall with a second space between the second surface and the second wall.

2. The display assembly according to claim 1 , wherein the protruding portion has a height equal to a thickness of the first polarizing plate.

3. The display assembly according to claim 1 , further comprising an adhesive member interposed between the protective member and the first polarizing plate and configured to bond the protective member to the first polarizing plate, wherein

the adhesive member includes a second through hole overlapping and communicating with the first through hole, and

the protruding portion is inserted in the first through hole and the second through hole.

4. The display assembly according to claim 3 , wherein the protruding portion has a height equal to a sum of a thickness of the first polarizing plate and a thickness of the adhesive member.

5. The display assembly according to claim 1 , further comprising a second polarizing plate disposed on an opposite side of the substrate to the protective member and configured to add a polarizing effect,

wherein the second polarizing plate has a third through hole overlapping the first through hole.

6. A display device comprising:

a display assembly according to claim 1 ; and

a lighting device disposed on the back side of the display assembly and configured to irradiate the display assembly with light, wherein

the lighting device has an accommodation space configured to accommodate an external component, and

the accommodation space is overlapping the first through hole.

7. The display device according to claim 6 , wherein the accommodation space is formed from an internal space of a hole portion extending through the lighting device.

8. A display assembly to be used for a display device, the display assembly comprising:

a substrate;

a protective member configured to protect the substrate;

a first polarizing plate disposed between the substrate and the protective member and configured to add a polarizing effect; and

an adhesive member interposed between the protective member and the first polarizing plate and configured to bond the protective member to the first polarizing plate, wherein

the first polarizing plate has a first through hole through which light passes toward a back side of the display assembly,

at least one of the substrate and the protective member includes a protruding portion having light transmissivity and protruding toward the first through hole,

the adhesive member includes a second through hole overlapping and communicating with the first through hole, and

the protruding portion is inserted in the first through hole and the second through hole.

9. The display assembly according to claim 8 , wherein the protruding portion has a height equal to a sum of a thickness of the first polarizing plate and a thickness of the adhesive member.

10. The display assembly according to claim 8 , wherein the protruding portion is integrally provided with at least one of the substrate and the protective member.

11. The display assembly according to claim 8 , further comprising a second polarizing plate disposed on an opposite side of the substrate to the protective member and configured to add a polarizing effect,

wherein the second polarizing plate has a third through hole overlapping the first through hole.

12. A display device comprising:

a display assembly according to claim 8 ; and

a lighting device disposed on the back side of the display assembly and configured to irradiate the display assembly with light, wherein

the lighting device has an accommodation space configured to accommodate an external component, and

the accommodation space is overlapping the first through hole.

13. The display device according to claim 12 , wherein the accommodation space is formed from an internal space of a hole portion extending through the lighting device.

14. A display assembly to be used for a display device, the display assembly comprising:

a substrate;

a protective member configured to protect the substrate;

a first polarizing plate disposed between the substrate and the protective member and configured to add a polarizing effect; and

a second polarizing plate disposed on an opposite side of the substrate to the protective member and configured to add a polarizing effect, wherein

the first polarizing plate has a first through hole through which light passes toward a back side of the display assembly,

at least one of the substrate and the protective member includes a protruding portion having light transmissivity and protruding toward the first through hole, and

the second polarizing plate has a third through hole overlapping the first through hole.

15. The display assembly according to claim 14 , wherein the protruding portion has a height equal to a thickness of the first polarizing plate.

16. The display assembly according to claim 14 , further comprising an adhesive member interposed between the protective member and the first polarizing plate and configured to bond the protective member to the first polarizing plate, wherein

the adhesive member includes a second through hole overlapping and communicating with the first through hole, and

the protruding portion is inserted in the first through hole and the second through hole.

17. The display assembly according to claim 16 , wherein the protruding portion has a height equal to a sum of a thickness of the first polarizing plate and a thickness of the adhesive member.

18. The display assembly according to claim 14 , wherein the protruding portion is integrally provided with at least one of the substrate and the protective member.

19. A display device comprising:

a display assembly according to claim 14 ; and

a lighting device disposed on the back side of the display assembly and configured to irradiate the display assembly with light, wherein

the lighting device has an accommodation space configured to accommodate an external component, and

the accommodation space is overlapping the first through hole.

20. The display device according to claim 19 , wherein the accommodation space is formed from an internal space of a hole portion extending through the lighting device.

21. The display assembly according to claim 1 , wherein the protruding portion is a portion of the at least one of the substrate and the protective member and does not contact walls of the first polarizing plate opposing the protruding portion.
