The invention discloses a special-shaped display panel and a display device. A display area of the special-shaped display panel has a special-shaped boundary, the display panel includes low-luminancepixels and conventional pixels, and the conventional pixels are arranged away from the special-shaped boundary; multiple pixels form multiple pixel rows and multiple pixel lines, the pixel rows or thepixel lines comprise pixel groups, the pixel groups comprise the first pixel groups and the second pixel groups, the number of pixels adjacent to the special-shaped boundary in the first pixel groupsis larger than that of pixels adjacent to the special-shaped boundary in the second pixel groups, and the number of low-luminance pixels in the first pixel groups is larger than that of low-luminancepixels in the second pixel groups; each pixel comprises at least three sub-pixels, electrodes are arranged in the sub-pixels, and each electrode is provided with at least one slit; in the same pixelgroup, in the direction from the special-shaped boundary to the display area, the angles and/or numbers of slits in the electrodes of the sub-pixels in the low-luminance pixels are gradually increased. By means of the special-shaped display panel and the display device, the phenomenon of jaggies in a special-shaped display panel is relieved.
