Abstract
An LCD includes a backlight module, an array substrate, and a color filter layer. The color filter layer includes a first filter unit, a second filter unit and a black matrix unit. A transmittance rate of the second filter unit is larger than that of the first filter unit. The black matrix layer is connected between the first filter unit and second filter unit. The width of the black matrix unit is larger than that of the third black matrix unit. The width of the black matrix unit facing the first filter unit is larger than that of the black matrix unit facing the second filter unit. This kind of asymmetrical black matrix layer not only best prevents lowering the pixel aperture ratio, but also improves color shift of images when light goes through pixels of low transmittance as pixels of high transmittance are turned off.
