Abstract

A seal pattern on a substrate for a liquid crystal display device includes a plurality of main seal patterns along first and second direction, a dummy seal pattern between the adjacent main seal patterns along the first direction, a first sub-seal pattern surrounding the plurality of main seal patterns, and a second sub-seal pattern at an exterior of the first sub-seal pattern, the second sub-seal pattern corresponding to a borderline between the adjacent main seal patterns along the second direction.

Claims (26)

1. A method of fabricating liquid crystal display unit panels, comprising:

forming a plurality of unit panels along first and second directions of a first substrate, wherein unit panels are spaced apart from each other along the first direction by a predetermined space, and wherein unit panels adjoin each other along the second direction, the forming of the plurality of unit panels including forming a plurality of main seal patterns to define a plurality of active areas;

forming a sub-seal pattern surrounding the plurality of unit panels;

attaching a second substrate over the first substrate;

curing the main seal pattern and the sub-seal pattern; and

cutting the attached first and second substrates into a plurality of unit panels.

2. The method of fabricating liquid crystal display unit panels of claim 1 , further comprising:

forming an additional sub-seal pattern at an exterior of the sub-seal pattern, the additional sub-seal pattern corresponding to a borderline between the adjacent main seal patterns disposed along the second direction.

3. The method of fabricating liquid crystal display unit panels of claim 2 , wherein the additional sub-seal pattern includes two parallel lines.

4. The method of fabricating liquid crystal display unit panels of claim 2 , wherein the sub-seal pattern and the additional sub-seal pattern include a thermosetting resin.

5. The method of fabricating liquid crystal display unit panels of claim 4 , wherein the sub-seal pattern and additional sub-seal pattern include a glass fiber.

6. The method of fabricating liquid crystal display unit panels of claim 1 , wherein each of the plurality of main seal patterns has an injection hole.

7. The method of fabricating liquid crystal display unit panels of claim 1 , further comprising:

forming a plurality of dummy seal patterns within the predetermined space between each of the unit panels along the first direction.

8. The method of fabricating liquid crystal display unit panels of claim 7 , wherein each dummy seal pattern includes a first dummy seal pattern and a second seal dummy seal pattern.

9. The method of fabricating liquid crystal display unit panels of claim 8 , wherein each of the plurality of main seal patterns has an injection hole and wherein the first dummy seal pattern is disconnected at a region adjacent to the injection hole.

10. The method of fabricating liquid crystal display unit panels of claim 1 , wherein the cutting includes separating the predetermined space from the unit panels.

11. A method of fabricating liquid crystal display unit panels, comprising:

forming a plurality of main seal patterns along first and second directions on a first substrate to define a plurality of active areas;

attaching a second substrate over the first substrate; and

cutting the attached first and second substrates into a plurality of unit panels, the cutting including:

forming a single cutting line between the plurality of main seal patterns adjacent to each other along the first direction; and

forming two cutting lines between the plurality of main seal patterns adjacent to each other along the second direction.

12. The method of fabricating liquid crystal display unit panels of claim 11 , further including forming a sub-seal pattern surrounding the plurality of main seal patterns.

13. The method of fabricating liquid crystal display unit panels of claim 11 , wherein each of the plurality of main seal patterns has an injection hole.

14. The method of fabricating liquid crystal display unit panels of claim 11 , further comprising forming a dummy seal pattern between the two cutting lines formed between the plurality of main seal patterns adjacent to each other along the second direction.
