A display panel and a display device are provided. The display panel includes a first area, a second area, and a third area. A first distance is greater than or equal to a second distance, and a fourth distance is greater than or equal to a third distance. The first distance, the second distance, the third distance, and the four distance are measured by a length of an orthographic projection on a flexible substrate that a first side and a second side of each of black matrices in the first area and the second area exceed corresponding sides of corresponding data lines, respectively.
