Abstract
A display panel and a display device are provided. Moisture and oxygen can be effectively prevented from passing through an organic light emitting layer in a barrier area and entering the organic light emitting layer in a display area of the display panel by disposing the barrier area having a plurality of trenches between the display area and a through hole and forming a blocking structure through disposing a barrier block between adjacent trenches. In addition, the trenches can be set into a wavy shape, which can increase an area of the trenches and further increase a surface area of a packaging layer in the barrier area, so that intrusion of moisture and oxygen can be effectively blocked, thereby protecting the display area and improving stability of the display device.
