A display panel and a display device are provided. The display panel includes a plurality of pixel units, which includes a first pixel unit and a second pixel unit. The first and second pixel units are adjacently arranged in a vertical direction. The first pixel unit includes a first subpixel, and the second pixel unit includes a second subpixel corresponding to the first subpixel. The first subpixel includes a first region and a second region which are vertically arranged. The second region arranged closer to the second subpixel with respect to the first region includes a third region. A transmittance of the first region is smaller than a transmittance of the second region, and the ratio of the area of the second region to the area of the third region is smaller than or equal to 4:6 and greater than or equal to 3:7.
