Abstract
The present disclosure provides a display panel and a display device. The display panel includes a display area, a transmitted subregion, a substrate, an array layer, a first barrier wall, a second barrier wall, a light emitting layer, and a boss. The boss includes a plurality of step layers. The light emitting layer covers the boss and is discontinuous at the boss. The barrier walls and the boss prevent external substances from entering the panel through film layers, thereby effectively preventing continued diffusion of water vapor to protect the display panel.
