Abstract

A display panel and a display device are disclosed. The display panel includes a first electrode layer, a light-emitting layer, and a second electrode layer sequentially stacked. The light-emitting layer includes first pixels disposed in a display light-transmitting region and second pixels disposed in a main display region. A first opening between the first pixels adjacent to each other is defined by the second electrode layer. A thickness of the light-emitting layer corresponding to the first opening is less than a thickness of the light-emitting layer between the second pixels adjacent to each other. Not only can the light transmittance of the display light-transmitting region be increased, but the process can be simpler.
