A display panel and a display device, related to the field of display technology. The display panel includes a first sub-pixel, a first pixel circuit, a second sub-pixel and a second pixel circuit. The first sub-pixel and the second sub-pixel have the same luminous color. When the display panel is configured to display a same frame of image, the first sub-pixel is driven by the first pixel circuit to emit light, or the second sub-pixel is driven by the second pixel circuit to emit light. In this case, when multiple frames of images are continuously displayed by the display panel, the first sub-pixel and the second sub-pixel can emit light alternately, such that the service life of the display panel can be prolonged, and the performance and competitiveness of the product can be improved.
