The pixel in a transflective color LCD panel of the present invention has an additional sub-pixel area. According to the present invention, a pixel is selectively divided into at least three color sub-pixels in R, G, B and a fourth sub-pixel M. Each of the color sub-pixels R, G and B is selectively divided into a transmission area and a reflection area. The fourth sub-pixel M can be entirely reflective or partially reflective. The color filter for use in the pixel comprises R, G, B color filter ...
