A flat panel display is disclosed. The display includes an array substrate, and a color filter substrate. The array substrate includes a plurality of pixel units, and each pixel unit includes at least three sub-pixels. The color filter substrate is placed opposite to a pixel array and includes a red resist, a green resist and a blue resist which respectively correspond to the sub-pixels. A ratio of thicknesses of the red, green and blue resists is configured in such a way that a ratio of total transmittances of the sub-pixels corresponding to the red, green and blue resists has a preset value.
