Abstract

The embodiment of the invention provides an organic light-emitting display panel and an organic light-emitting display device, relates to the technical field of display, and aims to reduce influence of a camera assembly on leakage current in pixels and improve display performance. The organic light-emitting display panel comprises a substrate base plate, a display area including an optical component setting area, a pixel comprising a first pixel, and a shading structure, wherein the first pixel comprises a first pixel circuit, the first pixel circuit comprises a first transistor, the first transistor is located in the optical component setting area, the first transistor comprises an active layer, a gate layer and a source-drain layer which are sequentially stacked in the direction away from the substrate, the active layer comprises a channel region, the shading structure is located in the optical component setting area, the shading structure is located on a side, away from a light-emitting surface of the organic light-emitting display panel, of the active layer, the shading structure comprises a first shading layer, and the channel region is completely overlapped with the first shading layer in the direction perpendicular to a plane where the substrate is located.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and an organic light emitting display device. 【Background technique】 [0002] An organic light-emitting display device with a camera function generally includes an organic light-emitting display panel and a camera assembly, wherein an optical component installation area is arranged in the organic light-emitting display panel, and the optical component installation area corresponds to the installation position of the camera assembly. However, when the camera assembly is shooting, the optical components in the camera assembly will emit light with high intensity, which will affect the leakage current of the pixels in the optical component setting area, thereby affecting the normal display. 【Content of invention】 [0003] In view of this, the embodiments of the present invention provide an organic light emitting display panel and a...
