Abstract

A liquid crystal display device that comprises a light-emitting source emitting light, and a reflector further comprising a base and a plurality of sidewalls extending from the base, wherein each of the sidewalls further comprises a multi-angle surface, in conjunction with the base, reflecting the emitted light toward a diffusion plate diffusing the reflected light.

Claims

1. A liquid crystal display device comprising:

a light-emitting source emitting light; and

a reflector further comprising a base and a plurality of sidewalls extending from the base,

wherein each of the sidewalls further comprises a multi-angle surface, in conjunction with the base, reflecting the emitted light toward a diffusion plate diffusing the reflected light.

2. The device of claim 1, the light emitting source further comprising a lamp.

3. The device of claim 1, the light emitting source further comprising a fluorescent lamp attached in the reflector.

4. The device of claim 1, the diffusion plate being made of acrylic resin.

5. The device of claim 1, the multi-angle surface being an infinite-angle surface.

6. The device of claim 1, the light emitting source, the reflector and the diffusion plate forming a backlight assembly for the liquid crystal display device.

7. The device of claim 1 further comprising a frame accommodating the light emitting source and the reflector.

8. The device of claim 7, the frame further comprising:

a base portion mounting the reflector; and

a plurality of sidewall portions extending from the base portion and supporting the diffusion plate.

9. The device of claim 1 further comprising a plurality of optical sheets formed on the diffusion plate.

10. The device of claim 1 further comprising:

a prism sheet formed on the diffusion plate; and

a diffusion sheet formed on the prism sheet.

11. A liquid crystal display device comprising:

a light-emitting source emitting light;

a multi-angle reflector for reflecting the emitted light; and

a diffusion plate for diffusing the reflected light.

12. The device of claim 11, the reflector further comprising:

a base formed substantially parallel to the light emitting source;

a plurality of sidewalls extending from the base; and

each of the sidewalls further comprising a multi-angle surface, in conjunction with the base, reflecting the emitted light toward the diffusion plate.

13. The device of claim 11, the light emitting source further comprising a lamp.

14. The device of claim 11, the light emitting source further comprising a cold cathode fluorescent lamp.

15. The device of claim 11, the diffusion plate being made of acrylic resin.

16. The device of claim 11, the multi-angle surface further comprising an infinite-angle surface and curved surface.

17. The device of claim 11 further comprising a frame accommodating the light emitting source and the reflector.

18. The device of claim 17, the frame further comprising:

a base portion mounting the reflector; and

a plurality of sidewall portions extending from the base portion and supporting the diffusion plate.

19. The device of claim 11 further comprising a plurality of optical sheets formed on the diffusion plate.

20. The device of claim 11 further comprising:

a prism sheet formed on the diffusion plate; and

a diffusion sheet formed on the prism sheet.
