Abstract
The present invention relates to a color filter with mosaic pixel array arrangement. The color filter comprises a plurality of pixel arrays. The pixel array has four sub-pixels. The color of the sub-pixel of the pixel array is identical to that of another sub-pixel of another pixel array adjacent to the pixel array. The sub-pixels with same color form a sub-pixel group so that the area of a single color of the sub-pixel group is increased. Therefore, the adhesion strength between the sub-pixel group and the substrate can be augmented to avoid peeling from the substrate. According to the invention, the yield rate of the product will be raised and the chromaticity will be improved.
