Abstract

A mother glass and a method of fabricating a liquid crystal display panel using the mother glass provides improved color characteristics and brightness. The mother glass is provided with a plurality of color filter arrays that include at least one block pattern located at a dummy region between the color filter arrays for substantially preventing the movement of color resin on the mother glass.

Claims (40)

1. A mother glass comprising:

a plurality of color filter arrays each including a black matrix and a color filter;

at least one block pattern formed in the path where a color resin runs to the middle of the mother glass; and

a common electrode and an alignment film formed on an entire the mother glass having the color filter and the block pattern,

wherein the block pattern comprises the same material as the black matrix,

wherein the path is located at a dummy region between adjacent color filter arrays,

wherein the block pattern and the black matrix are formed simultaneously,

wherein the block pattern is positioned so as to partition the mother glass into each region having the color filter array,

wherein the block pattern serves to block the color resin from running down the middle of the mother glass during fabrication of the color filter, and

wherein the color resin is prevented from collecting in the middle of the mother glass.

2. The mother glass according to claim 1 , wherein the block pattern has a thickness of 1.0 μm to about 1.5 μm.

3. The mother glass according to claim 1 , wherein the block pattern has a line width of about 40 μm to about 70 μm.

4. A method of manufacturing a liquid crystal display panel comprising:

forming a black matrix at an array regions of a mother glass and forming at least one block pattern in the path where a resin runs to the middle of the mother glass for substantially preventing movement of the resin;

forming a color filter in the array region; and

forming a common electrode and an alignment film on an entire the mother glass having the color filter and the block pattern,

wherein the block pattern comprises the same material as the black matrix,

wherein the path is located at a dummy region between the array regions,

wherein the block pattern and the black matrix are formed simultaneously,

wherein the block pattern is positioned so as to partition the mother glass into each region having the color filter array,

wherein the block pattern serves to block the color resin from running down the middle of the mother glass during fabrication of the color filter, and

wherein the color resin is prevented from collecting in the middle of the mother glass.

5. The method according to claim 4 , wherein the block pattern has a thickness of about 1.0 μm to about 1.5 μm.

6. The method according to claim 4 , wherein the block pattern has a line width of about 40 μm to about 70 μm.

7. The method according to claim 4 , further comprising:

preparing a second mother glass having a thin film transistor array formed thereon and facing to the mother glass;

combining the mother glass and the second mother glass; and

cutting the combined mother glasses to form a plurality of liquid crystal display panels.

8. A method of manufacturing a liquid crystal display panel comprising:

providing a substrate having a first array region spaced apart from a second array region by a dummy region;

forming a black matrix in the first and second array regions;

forming at least one block pattern in the dummy region applying a color resin on the substrate forming a color filter in the substrate; and

forming a common electrode and an alignment film on an entire the substrate having the color filter and the block pattern,

wherein the block pattern substantially prevents the color resin from collecting on the substrate during processing,

wherein the block pattern and the black matrix are formed simultaneously,

wherein the block pattern comprises the same material as the black matrix,

wherein the block pattern is positioned so as to partition the mother glass into each region having the color filter array,

wherein the block pattern serves to block the color resin from running down the middle of the mother glass during fabrication of the color filter, and

wherein the color resin is prevented from collecting in the middle of the mother glass.

9. The method according to claim 8 further comprising subjecting to substrate to bending conditions during processing.
