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

1. A seal pattern on a substrate for a liquid crystal display device, comprising:

a plurality of main seal patterns defining a plurality of unit panels on a substrate and disposed along first and second directions, wherein each main seal pattern defines a unit panel;

a sub-seal pattern having a closed shape and surrounding the plurality of unit panels; and

a dummy seal pattern only between the adjacent main seal patterns along the first direction, wherein the unit panels are spaced apart from each other along the first direction by a predetermined space, and the unit panels adjoin each other along the second direction, wherein two cutting lines are formed between the adjacent main seal patterns along the first direction, and one cutting line is formed between the adjacent main seal patterns along the second direction.

2. The seal pattern of claim 1, wherein each main seal pattern has an injection hole.

3. The seal pattern of claim 1, wherein the dummy seal pattern includes a first dummy seal pattern and a second seal dummy seal pattern.

4. The seal pattern of claim 3, wherein the first dummy seal pattern is disconnected at a region corresponding to an injection hole.

5. The seal pattern of claim 1, wherein the sub-seal pattern includes a thermosetting resin.

6. The seal pattern of claim 5, wherein the sub-seal pattern include a glass fiber.
