A liquid crystal display includes a first substrate and a second substrate, a liquid crystal layer disposed between the first and second substrate, and a backlight module disposed under the second substrate. The first substrate comprises color filters disposed in array, wherein each color filter has a chromaticity-adjusting region; a thickness of the color filters and a size of the chromaticity-adjusting region are adjustable for adjusting the chromaticity of the LCD. The second substrate comprises pixel electrodes corresponding to the color filters. Therefore, the liquid crystal display can easily adjust and perfect the chromaticity of the liquid crystal display under the restrictions of the material of the color filters, the backlight module, and the design thereof.
