The first color resistor comprises a plurality of blocks. The second color resistor comprises a plurality of blocks. The third resistor comprises a plurality of blocks. In the top view, the blocks of the first color resist are arranged in a continuous S shape in common, the blocks of the second color resist are arranged in a continuous S shape in common, and the blocks of the third color resist are arranged in a continuous S shape in common. The color filter array of the present disclosure can maintain the color gamut size and color white balance of the display. By dividing the color resistance into a plurality of continuous but non-overlapping blocks, the overall brightness of the display picture can be improved, and the probability of lines which can be recognized by human eyes in the display picture can be reduced. The S-shaped grain arrangement can also be regarded as a simulation of the actual paper fiber grain.
