Abstract

Provided are a hollow mold for receiving a liquid crystal panel and a diffuser plate, the hollow mold capable of automating an assembling process of a liquid crystal display (LCD) and fixing a reflective sheet, and an LCD including the hollow mold. The hollow mold includes an outer side surface; a top surface; an inner side surface comprising a first step which is formed in a stepped shape, defines an upper receiving space and performs a supporting function, a second step which defines a lower receiving space and performs the supporting function, and an inclined surface which slopes downward from the second step; and a bottom surface.

Claims (30)

1. A hollow mold for receiving a liquid crystal panel and a diffuser plate, the hollow mold comprising:

an outer side surface;

a top surface;

an inner side surface comprising a first step which is formed in a stepped shape to define an upper receiving space, a second step which is integrally formed with the first step to define a lower receiving space, and at least a pair of inclined surfaces facing each other which slope downward from the second step; and

a bottom surface,

wherein the second step protrudes further inward of the hollow mold than the first step.

2. The hollow mold of claim 1 , wherein the inclined surface is formed of a light reflecting material.

3. The hollow mold of claim 2 , wherein the inclined surface further comprises a fixing portion parallel to the bottom surface.

4. The hollow mold of claim 1 , wherein each of a pair of inclined surfaces of the inclined surfaces facing each other comprises a plurality of through-grooves in a lower portion thereof.

5. The hollow mold of claim 4 , wherein the bottom surface comprises a concavo-convex surface having two concave portions.

6. The hollow mold of claim 1 , further comprising a plurality of coupling grooves in the outer side surface.

7. A liquid crystal display (LCD) comprising:

a liquid crystal panel;

a diffuser plate;

a hollow mold adapted to receive the liquid crystal panel disposed in an upper receiving space and the diffuser plate disposed in a lower receiving space, the hollow mold comprising an outer side surface, a top surface, an inner side surface comprising a first step which is formed in a stepped shape to define the upper receiving space, a second step which is integrally formed with the first step to define the lower receiving space, and at least two a pair of inclined surfaces facing each other which slope downward from the second step, and a bottom surface;

a support disposed under the diffuser plate;

a reflective flat sheet for reflecting light disposed under the support; and

a bottom chassis coupled to the hollow mold and holding the hollow mold, the support and the reflective sheet,

wherein the second step protrudes further inward of the hollow mold than the first step.

8. The LCD of claim 7 , wherein the inclined surface fixes the reflective sheet.

9. The LCD of claim 8 , wherein the inclined surface further comprises a fixing portion formed parallel to the bottom surface and adapted to fix the reflective sheet.

10. The LCD of claim 9 , wherein the inclined surface is formed of a light reflecting material.

11. The LCD of claim 10 , wherein a center part of the reflective sheet is fixed by the support.

12. The LCD of claim 7 , wherein each of a pair of inclined surfaces of the inclined surfaces facing each other comprises a plurality of through-grooves in a lower portion thereof.

13. The LCD of claim 12 , wherein the bottom surface comprises a concavo-convex surface having two concave portions.

14. The LCD of claim 7 , further comprising a plurality of coupling grooves in the outer side surface.

15. The LCD of claim 14 , wherein the bottom chassis further comprises a plurality of coupling protrusions coupled to the coupling grooves.

16. The LCD of claim 11 , further comprising an optical sheet disposed on the diffuser plate and directly contacting the liquid crystal panel.

17. The LCD of claim 11 , further comprising an optical sheet disposed on the diffuser plate and adhered to the liquid crystal panel using an adhesive layer.

18. The LCD of claim 11 , further comprising an optical sheet disposed on the diffuser plate and a spacer disposed on the optical sheet to separate the optical sheet from the liquid crystal panel.
