Display apparatus

1. A display apparatus comprising:

a display panel;

a light guide plate configured to guide light to the display panel and disposed behind the display panel;

a light source configured to emit light to a lateral surface of the light guide plate;

a diffusion plate disposed between the display panel and the light guide plate; and

at least one support member configured to support the diffusion plate and disposed to pass through the light guide plate,

wherein a light transmittance of a first portion of the at least one support member at a side of the at least one support member facing the light source is different from a light transmittance of a second portion of the at least one support member forming a side opposite to the side of the at least one support member facing the light source.

2. The display apparatus as claimed in claim 1 , wherein the light guide plate includes at least one insertion hole to which the at least one support member is coupled,

wherein the at least one support member comprises an insertion portion inserted into the at least one insertion hole, a cover portion that contacts a light output surface of the light guide plate and covers the at least one insertion hole, and a support portion that supports the diffusion plate, and

wherein a light transmittance of a portion of the cover portion at the side of the at least one support member facing the light source is lower than a light transmittance of a remaining portion of the cover portion.

3. The display apparatus as claimed in claim 2 , wherein a diameter of the cover portion is larger than a diameter of the at least one insertion hole to cover a surrounding portion of the at least one insertion hole, and

wherein the insertion portion protrudes toward the at least one insertion hole from a center of the cover portion.

4. The display apparatus as claimed in claim 3 , wherein the cover portion comprises the first portion, and the second portion, and

wherein the light transmittance of the first portion is lower than the light transmittance of the second portion.

5. The display apparatus as claimed in claim 4 , wherein the cover portion comprises a plate positioned parallel to the light output surface.

6. The display apparatus as claimed in claim 5 , wherein the cover portion comprises a circular plate, and

wherein the first portion has a circular sector shape with respect to a center of the at least one insertion hole, and

wherein the second portion has a complementary circular sector shape to the circular sector shape of the first portion.

7. The display apparatus as claimed in claim 6 , wherein a central angle of the first portion is smaller than a central angle of the second portion.

8. The display apparatus as claimed in claim 4 , wherein the first portion comprises a light-blocking material; and

wherein the second portion comprises a light-transmissive material.

9. The display apparatus as claimed in claim 8 , wherein the first portion is white and the second portion is transparent.

10. The display apparatus as claimed in claim 8 , wherein the insertion portion comprises the light-blocking material.

11. The display apparatus as claimed in claim 10 , wherein the first portion and the insertion portion are integrally formed with each other.

12. The display apparatus as claimed in claim 4 , wherein the first portion comprises a reflective lens configured to reflect light discharged from the at least one insertion hole.

13. The display apparatus as claimed in claim 4 , wherein the first portion comprises a diffusion lens configured to diffuse light discharged from the at least one insertion hole.

14. The display apparatus as claimed in claim 2 , wherein the support portion protrudes toward the diffusion plate from a center of the cover portion.

15. The display apparatus as claimed in claim 14 , wherein the support portion comprises an arch-shaped buffer portion with opposite ends coupled to the cover portion and a support protrusion coupled to the buffer portion to support the diffusion plate.

16. A display apparatus comprising:

a light guide plate;

a diffusion plate;

a light source configured to emit light toward a side surface of the light guide plate; and

a support member comprising:

a contact portion configured to contact a rear surface of the diffusion plate;

a fitting portion configured to fit into a hole provided in the light guide plate; and

a disk portion configured to rest on a front surface of the light guide plate,

wherein the disk portion comprises a first region provided closer to the light source than a second region of the disk portion, the second region forming an opposite side of the disk portion from a side of the first region, and

wherein a light transmittance of the first region is lower than a light transmittance of the second region.

17. The display apparatus as claimed in claim 16 , further comprising a display panel provided in front of the diffusion plate.

18. The display apparatus as claimed in claim 16 , further comprising a chassis provided behind the light guide plate,

wherein the fitting portion of the support member is further configured to fit into a hole provided in the chassis.

19. The display apparatus as claimed in claim 16 , wherein the first region of the disk portion comprises a partial reflective lens.

20. The display apparatus as claimed in claim 16 , wherein a refraction groove is formed in the first region of the disk portion.
