Abstract

An LCD device for repairing to prevent gravity defects by forming a dual seal pattern in a non-display area of an LCD panel and storing surplus liquid crystal in an area between the dual seal patterns, which includes a liquid crystal panel including first and second substrates bonded to each other, and having a display area and non-display area, first and second seal patterns surrounding the display area and spaced apart from each other on the non-display area between the first and second substrates and defining a buffer space therebetween and a metal pattern formed on the first substrate under the first seal pattern, wherein the metal pattern is deformed by laser irradiation to form a path for liquid crystal to flow between the buffer space and the display area.

Claims (14)

1. A liquid crystal display (LCD) device comprising:

a liquid crystal panel including first and second substrates bonded to each other, and having a display area and non-display area;

first and second seal patterns surrounding the display area and spaced apart from each other on the non-display area between the first and second substrates and defining a buffer space therebetween; and

a metal pattern formed on the first substrate under the first seal pattern, wherein the metal pattern is deformed by laser irradiation to form a path for liquid crystal to flow between the buffer space and the display area.

2. The LCD device of claim 1 , wherein the path is configured for surplus liquid crystal when liquid crystal is oversupplied between the first and second substrate.

3. The LCD device of claim 1 , wherein the metal pattern includes at least one path for liquid crystal to flow to the buffer space.

4. The LCD device of claim 1 , wherein the first substrate includes a plurality of gate lines and data lines crossing each other in the display area.

5. The LCD device of claim 4 , wherein the metal pattern comprises substantially the same material as the gate lines.

6. The LCD device of claim 5 , wherein the metal pattern is formed on the same layer as the gate lines.

7. The LCD device of claim 4 , wherein the metal pattern comprises substantially the same material as the data lines.

8. The LCD device of claim 7 , wherein the metal pattern is formed on the same layer with the data lines.

9. The LCD device of claim 1 , wherein the first substrate includes gate pad and data pad in the non-display area.

10. The LCD device of claim 9 , wherein the metal pattern is formed on the first substrate having no gate and data pads of the LCD panel.

11. The LCD device of claim 1 , further comprising an insulating layer between the metal pattern and the first and second seal patterns.
