Abstract

The invention provides a display panel and a display device, relates to the technical field of display, and is used for reducing the intensity of light emitted from one side, far away from a light emitting unit, of a substrate in the display panel. The display panel comprises a light emitting unit, a pixel definition layer and a light shielding layer. The light emitting unit includes a first electrode, a second electrode, and a light emitting layer. The pixel definition layer comprises an opening part and a non-opening part, and at least part of the light-emitting layer is located in the opening part; the first electrode is located in the opening part in the direction perpendicular to the plane where the substrate is located; the opening part comprises a first opening close to the substrate and a second opening far away from the substrate; the shading layer is not overlapped with the first opening in the direction perpendicular to the plane where the substrate is located; orthographic projections of the shading layer and the first electrode on the plane where the substrate is located are a first projection and a second projection respectively; along the first direction, the difference value between the sum of the length of the first projection and the length of the second projection and the length of the second opening meets a preset threshold value.

Description

Technical field

[0001] The present invention relates to the field of display technology, in particular to a display panel and a display device.

Background technique

[0002] In recent years, with the continuous development of display technology, consumers' requirements for display screens have been continuously improved. At present, various displays including display screens such as liquid crystal display screens and self-luminous display screens emerge in an endless stream. On this basis, display technologies including touch display technology, curved surface display technology, under-screen camera technology, and under-screen fingerprint recognition technology continue to emerge.

[0003] A self-luminous display screen includes a light-emitting unit formed on one side of a substrate. At present, during the display process of the self-luminous display screen, in addition to propagating to the side of the light-emitting unit away from the substrate, the light emitted b...
