Abstract
An embodiment of the present disclosure discloses a display panel and a display device, wherein third openings are disposed in a region of a black matrix layer corresponding to a transition region in the display panel, so that external light can be reflected by the reflection structure through the third openings, to form reflected light, thereby increasing the light reflectivity of the transition region and improving the dimmer transition region when the panel is screen-off and screen-on.
