Abstract

A display panel comprises a display region, a non-display region, and a black matrix. The display region includes a plurality of pixels arranged in both a first direction and a second direction, where the plurality of pixels are arranged in the first direction to form a plurality of pixel rows and, meanwhile, arranged in the second direction to form a plurality of pixel columns, and a pixel includes a light-transmitting area. The black matrix does not overlap with the light-transmitting area. The display region includes at least one irregular edge intersecting both the first direction and the second direction. The plurality of pixels include a plurality of first pixels intersecting the at least one irregular edge and a plurality of second pixels without intersecting the at least one irregular edge, and the light-transmitting area of the first pixel is smaller than the light-transmitting area of the second pixel.
