Abstract

Provided are a display panel and a display device. The display panel includes a display region having a first steplike edge. The display region is provided with a plurality of sub-pixel groups. Each sub-pixel group includes a first sub-pixel unit, a second sub-pixel unit and a third sub-pixel unit. The first sub-pixel unit, the second sub-pixel unit and the third sub-pixel unit have different luminous colors. Along a connecting line of step apex angles of the first steplike edge, the display region is provided with a plurality of first sub-pixel groups and a plurality of second sub-pixel groups. The first sub-pixel unit in each first sub-pixel group is disposed at a step apex angle of the first steplike edge, and the second sub-pixel unit in each second sub-pixel group is disposed at the step apex angle of the first steplike edge.
