Abstract

A manufacturing apparatus of a liquid crystal display includes a spacer supply plate provided with a plurality of grooves into which spacers are injected, a transcribing roller into a surface of which the spacers are first-transcribed thereof, and a support plate mounting a panel into which the spacers on the surface of the transcribing roller are second-transcribed.

Claims (34)

1. A manufacturing apparatus of a liquid crystal display, comprising:

a spacer supply plate provided with a plurality of grooves in which spacers are injected;

a transcribing roller, wherein the spacers are first-transcribed onto a surface thereof; and

a support plate mounting a panel onto which the spacers on the surface of the transcribing roller are second-transcribed,

wherein each of the spacers comprises a plurality of sub-spacers having different sizes, the spacers are disposed separated from each other at a distance and the sub-spacers in each of the spacers substantially contact each other.

2. The manufacturing apparatus of claim 1 , wherein the grooves are disposed at a predetermined interval.

3. The manufacturing apparatus of claim 2 , wherein the spacers on the surface of the transcribing roller are disposed at an interval corresponding to an interval of the grooves.

4. The manufacturing apparatus of claim 1 , wherein the spacers are injected into the grooves along with a thermal curing agent, an ultra violet ray (UV) curing agent or both.

5. The manufacturing apparatus of claim 1 , wherein the difference of the sizes of the sub-spacers ranges from about 1 μm to about 3 μm.

6. The manufacturing apparatus of claim 1 , wherein the spacers comprise of a plurality of sub-spacers having different elasticities.

7. A manufacturing method of a liquid crystal display, comprising:

injecting spacers into a plurality of grooves formed in a spacer supply plate;

first-transcribing the spacers in the grooves onto a surface of a transcribing roller; and

second-transcribing the spacers on the surface of the transcribing roller onto a first panel,

wherein each of the spacers comprises a plurality of sub-spacers having different sizes, the spacers being disposed separated from each other at a distance and the sub-spacers in each of the spacers substantially contact each other.

8. The manufacturing method of claim 7 , wherein the spacers second-transcribed onto the first panel comprise a thermal curing agent, a UV curing agent or both.

9. The manufacturing method of claim 8 , further comprising attaching the spacers to the first panel by heat, by UV or both.

10. The manufacturing method of claim 7 , further comprising attaching the first panel to a second panel.

11. The manufacturing method of claim 7 , further comprising attaching the first panel to a second panel, the spacers being disposed between the first panel and the second panel, wherein a sub-spacer having a larger size is compressed to have a size substantially equal to a sub-spacer having a smaller size.

12. The manufacturing method of claim 11 , wherein a cell gap between the first and second panels is determined by the sub-spacer having the smaller size.

13. The manufacturing method of claim 7 , wherein the grooves are disposed at a predetermined interval.

14. The manufacturing method of claim 7 , wherein the spacers on the surface of the transcribing roller are disposed at an interval corresponding to an interval of the grooves.

15. A manufacturing method of a liquid crystal display, comprising:

injecting spacers into a plurality of grooves formed in a spacer supply plate;

first-transcribing the spacers in the grooves onto a surface of a transcribing roller; and

second-transcribing the spacers on the surface of the transcribing roller onto a first panel,

wherein each of the spacers comprises a plurality of sub-spacers having different elasticities, the spacers being disposed separated from each other at a distance and the sub-spacers in each of the spacers substantially contact each other.

16. The manufacturing method of claim 15 , further comprising attaching the first panel to a second panel, the spacers being disposed between the first panel and the second panel, wherein a sub-spacer having a higher elasticity is pressed to have a size substantially equal to a sub-spacer having a lower elasticity.

17. The manufacturing method of claim 16 , wherein a cell gap between the first and second panels is determined by the sub-spacer having the lower elasticity.

18. The manufacturing method of claim 15 , wherein the grooves are disposed at a predetermined interval.

19. The manufacturing method of claim 15 , wherein the spacers on the surface of the transcribing roller are disposed at an interval corresponding to an interval of the grooves.

20. The manufacturing method of claim 15 , wherein the spacers second-transcribed onto the first panel comprise a thermal curing agent, a UV curing agent or both.

21. The manufacturing method of claim 20 , further comprising attaching the spacers to the first panel by heat, by UV or both.

22. The manufacturing method of claim 15 , further comprising attaching the first panel to a second panel by pressure.
