Abstract

A method of fabricating a liquid crystal display (LCD) panel, and a seal pattern forming device used in fabricating the same, applies both seal dispensing and screen printing techniques to form seal patterns of variously sized LCD panels formed on the same base substrate.

Claims (18)

1. A method of fabricating a liquid crystal display (LCD) panel, comprising:

providing a base substrate;

forming at least one first image display region within a first panel region of the base substrate;

forming at least one second image display region within a second panel region of the base substrate, wherein the at least one second image display region is smaller than the at least one first image display region, and wherein the second panel region is smaller than the first panel region;

forming at least one first seal pattern at a periphery of at least one first image display region by a seal dispensing method; and

forming at least one second seal pattern at a periphery of at least one second image display region by a screen printing method.

2. The method of claim 1 , wherein the first and second image display regions comprise TFT array substrates.

3. The method of claim 1 , wherein the first and second image display regions comprise color filter substrates.

4. The method of claim 1 , wherein forming at least one first seal pattern comprises forming a plurality of first seal patterns.

5. The method of claim 4 , further comprising forming the plurality of first seal patterns simultaneously.

6. The method of claim 1 , wherein forming at least one second seal pattern comprises forming a plurality of first seal patterns.

7. The method of claim 6 , further comprising forming the plurality of second seal patterns simultaneously.

8. The method of claim 1 , further comprising forming at least one second seal pattern after forming at least one first seal pattern.

9. The method of claim 1 , further comprising forming at least one first seal pattern after forming at least one second seal pattern.

10. A seal pattern forming device of a liquid crystal display (LCD) panel, comprising:

a first seal pattern former forming at least one first seal pattern on at least one first image display region within a first panel region of a base substrate by a seal dispensing method; and

a second seal pattern former forming at least one second seal pattern on at least one second image display region within a second panel region of the base substrate by a screen printing method,

wherein a size of the second panel region is smaller than the first panel region, and a size of the second image display region is smaller than the first image display region.
