Abstract: The present disclosure discloses a display panel and a display device. The display panel includes a base substrate including a first display region and a second display region. Since pixel circuits for driving light-emitting elements in the second display region are only disposed in the first display region but not disposed in the second display region, the light transmittance of the second display region is ensured to be good. Correspondingly, the display panel in the present disclosure has a good display effect.
