Abstract

A liquid crystal display panel device includes a liquid crystal display panel, a sealing material disposed along a first outer perimeter of the liquid crystal display panel, a barrier wall disposed along a second outer perimeter of the liquid crystal display panel, and a liquid crystal material disposed within the second outer perimeter of the liquid crystal display panel, wherein the first outer perimeter is greater than the second outer perimeter and at least one cavity space is formed between the first and second outer perimeters.

Claims (13)

1. A method for compensating for excess amounts of liquid crystal material within a liquid crystal display panel, comprising steps of:

determining an actual filling amount of a liquid crystal material to fill the liquid crystal display panel;

determining a set amount of the liquid crystal material designed to fill the liquid crystal display panel;

comparing the actual filling amount and the set amount; and

melting a barrier wall of the liquid crystal display panel based upon the step of comparing.

2. The method according to claim 1 , wherein the step of melting a barrier wall includes application of ultrasonic waves to the liquid crystal display panel.

3. The method according to claim 1 , wherein the step of melting a barrier wall includes application of light to the liquid crystal display panel.

4. The method according to claim 1 , wherein a sealing material is formed along a first outer perimeter of the liquid crystal display panel and the barrier wall is formed along a second outer perimeter of the liquid crystal display panel.

5. The method according to claim 4 , wherein the first outer perimeter is greater than the second outer perimeter.

6. The method according to claim 5 , wherein at least one cavity space is formed between the first and second outer perimeters.

7. The method according to claim 6 , wherein the step of melting a barrier wall allows a portion of the actual filling amount of the liquid crystal material to flow into the at least one cavity space.

8. The method according to claim 5 , wherein the barrier wall includes a plurality of lateral wall portions forming a plurality of cavity spaces between the first and second outer perimeters.

9. The method according to claim 8 , wherein the step of melting a barrier wall allows a portion of the actual filling amount of the liquid crystal material to flow into at least one of the plurality of cavity spaces.
