Abstract

A display device includes a plurality of data lines, a plurality of scan lines, and a pixel array. The pixel array is electrically coupled to the data lines and the scan lines. Colors of the sub pixels electrically coupled to the same scan line are the same. The pixel array includes a plurality of first color sub-pixel rows, a plurality of second color sub-pixel rows, and a plurality of third color sub-pixel rows. The third color sub-pixels corresponding to the same data line include a first sub-pixel and a second sub-pixel. The first sub-pixel and the second sub-pixel have different polarities. The sub-pixels configured between the first sub-pixel and the second sub-pixel have the same polarity.
