摘要： The disclosure provides a display panel and a display device, and belongs to the technical field of display. The disclosure provides a display panel including a central display region and a bent display region at an edge of the central display region. The central display region is provided with a plurality of first pixels, and the bent display region is provided with a plurality of second pixels. A number of second pixels in a unit area is greater than a number of first pixels in the unit area. In the display panel, the PPI of the bent display region is higher than that of the central display region, so the number of the second pixels for gray-scale transition in the bent display region is increased, the gray-scale transition in the bent display region is uniform, and the aliasing phenomenon at the edge of the bent display region is improved.
