Display substrate and display device including the same
A liquid crystal display device with improved display quality is provided. The liquid crystal display device includes a signal line formed on a first substrate to extend generally in a first direction, a color filter at least partially overlapping the signal line, a black matrix pattern separated from the color filters by a separation region, and a column spacer pattern formed on the separation region.
1 . A liquid crystal display device comprising:
a signal line formed on a first substrate to extend generally in a first direction;
a color filter at least partially overlapping the signal line;
a black matrix pattern separated from the color filter by a separation region; and
a column spacer pattern formed on the separation region.
2 . The liquid crystal display device of claim 1 , wherein the column spacer pattern includes a colored material to block light.
3 . The liquid crystal display device of claim 1 , wherein the column spacer pattern at least partially overlaps the color filter.
4 . The liquid crystal display device of claim 1 , wherein the column spacer pattern is formed on the black matrix pattern.
5 . The liquid crystal display device of claim 1 , further comprising a second substrate facing the first substrate; and
a liquid crystal layer interposed between the first substrate and the second substrate.
6 . The liquid crystal display device of claim 5 , wherein the color filter and the black matrix pattern are arranged on the first substrate.
7 . The liquid crystal display device of claim 5 , wherein:
the column spacer pattern includes a peripheral portion and a first column spacer protruding from the peripheral portion, and
a height of the first column spacer is larger than a height of the column spacer pattern that lies on the separation region.
8 . The liquid crystal display device of claim 7 , wherein the height of the first column spacer is at least about 7 μm larger than the height of the column spacer pattern that lies on the separation region.
9 . The liquid crystal display device of claim 1 , wherein:
the black matrix pattern at least partially overlaps the signal line, and the color filter and the black matrix pattern do not overlap each other.
10 . The liquid crystal display device of claim 1 , wherein the color filter is separated from the black matrix pattern by a first distance that is generally equal to or smaller than about 4 μm.
11 . The liquid crystal display device of claim 1 , further comprising a pixel electrode formed on the color filter,
wherein the pixel electrode comprises a negative organic film.
