Abstract

A display panel includes a base substrate and a plurality of sub-pixel groups. The plurality of sub-pixel groups includes a first sub-pixel group and a second sub-pixel group. The first sub-pixel group includes two adjacent sub-pixels with a first interval therebetween, and the second sub-pixel group includes two adjacent sub-pixels with a second interval therebetween. The first interval is different from the second interval.
