Abstract
A display panel and a display device are provided. An organic light-emitting layer includes a doped region and an undoped region, and the undoped region is located between the doped region and the hole blocking layer. When the display panel is in a low grayscale display state, an exciton concentration distribution curve of the organic light-emitting layer includes a first peak located in the doped region and a second peak located in the undoped region, and a peak value of the second peak is less than a peak value of the first peak.
