Abstract

The present application discloses a display panel and a display device, the display panel has a first display area and a second display area at least partially surrounding the first display area, the light transmittance of the first display area is greater than that of the second display area The display panel includes a substrate and a light-emitting device layer. The light-emitting device layer is formed on the substrate and includes a first electrode layer, a light-emitting layer and a second electrode layer that are stacked in a direction away from the substrate. The light-emitting layer includes a layer located in the first display area. a first light-emitting material layer and a second light-emitting material layer located in the second display area; the first light-emitting material layer includes a plurality of first sub-light-emitting material layers stacked in a direction perpendicular to the substrate, adjacent to the first sub-light-emitting material layer A connection layer is provided in between. In the display panel, the difference in luminous intensity between the first light-emitting display area and the second light-emitting display area is small, and the display effect is good.

Description

technical field [0001] The present application belongs to the technical field of display devices, and in particular, relates to a display panel and a display device. Background technique [0002] With the introduction of the concept of full-screen mobile phones, the under-screen camera has become a major trend in the future. In the existing design, after the brightness difference between the display area opposite to the camera and other display areas in the display screen is reduced, the service life of the display screen in the area opposite to the camera area is reduced. SUMMARY OF THE INVENTION [0003] The embodiments of the present application provide a display panel and a display device, in which the difference in luminous intensity between the first light-emitting display area and the second light-emitting display area is small, and the display effect is good. [0004] In one aspect, an embodiment of the present application provides a display panel having a first d...
