Abstract

A display panel with irregular shape and a display device. The display panel with irregular shape includes a plurality of first constant potential lines and a plurality of data lines with different lengths; and a display area is divided into a plurality of display subareas in the extending direction of the first constant potential lines, and at least one data line is arranged in each display subarea. For the different display subareas, a shorter one of the plurality of data lines in the display subareas is associated with a larger total overlapped area between this data line in the display subareas and the associated one of the plurality first constant potential lines.
