A liquid crystal display includes a color filter substrate having a red, green and blue color filters formed thereon as a matrix, a thin film transistor array substrate having liquid crystal cells of red, green and blue pixels corresponding to the red, green and blue color filters, wherein each liquid crystal cell has a thin film transistor and a liquid crystal layer between the color filter substrate and the thin film transistor array substrate, wherein a first channel width/length ratio is provided for a thin film transistor in the liquid crystal cell of a first color pixel that is different from a second channel width/length ratio provided for a thin film transistor in the liquid crystal cell of a second color pixel.
