Abstract

A display panel and a display device are provided. The display panel includes a substrate, a driving circuit layer, a planarization layer, and a light-emitting unit layer. The driving circuit layer is provided on a side of the substrate. The planarization layer is provided on a side of the driving circuit layer facing away from the substrate. The light-emitting unit layer is provided on a side of the planarization layer facing away from the driving circuit layer. The planarization layer includes a first planarization sublayer and a second planarization sublayer. The first planarization sublayer is arranged at least in a first region of the display panel. The second planarization sublayer is arranged at least in a second region of the display panel. Materials of the first planarization sublayer and the second planarization sublayer are different in composition.
