Color filter substrate and liquid crystal display apparatus having the same
View Patent ↗The LCD apparatus having a color filter substrate including a first area and a second area adjacent to the first area. The color filter substrate includes a plurality of color pixels having different colors with respect to each other. The color pixels have an element formed thereon to partially expose the substrate. A transmission electrode is formed on the color filter and on the substrate exposed through the element. At least two color pixels of the color pixels have different sizes from each other. Thus, the LCD apparatus has improved display properties.

a red (R), a green (G), and a blue (B) color filter formed in the color filter layer;
a first hole formed in the red (R) color filter;
a second hole formed in the green (G) color filter;
a third hole formed in the blue (B)color filter,
wherein the second hole is larger than the first hole.
2. The reflection-transmission LCD of claim 1 , wherein the third hole is smaller than the second hole.
3. The reflection-transmission LCD of claim 1 , wherein each of the red (R), green (G), and blue (B) color filters is divided into a first area and a second area arranged adjacent to each other and the first area does not contain the hole.
4. The reflection-transmission LCD of claim 3 , wherein the second area of the red (R) color filter comprises two holes.
