Embodiment 1

[0077] Embodiment 1: The edge of the first lens body 310 does not overlap with the pixel opening 220 where d>0.

Embodiment 2

[0078] Embodiment 2: The edge of the first lens body 310 overlaps with the pixel opening 220 in the region where d>0.

Embodiment 3

[0079] Embodiment 3: Part of the edge of the first lens body 310 does not overlap with the pixel opening 220 in the area where d>0, and another part of the edge of the first lens body 310 overlaps with the pixel opening 220 in the area where d>0.

[0080] see Figure 6 , Figure 6 A relative positional relationship between one of the pixel openings 220 and the first lens body 310 is schematically shown.

[0081] In Embodiment 1, optionally, the first lens body 310 includes a first body portion 311 and a plurality of first protrusions 312 protruding from the first body portion 311, and between two adjacent first protrusions 312 Including the first gap 313 , the distance between the edge of the orthographic projection of the first protrusion 312 on the substrate 100 and the edge of the pixel projection is zero, and the orthographic projection of the first protrusion 312 on the substrate 100 does not overlap with the pixel projection. like Figure 6 As shown, the isolation str...

Abstract

The embodiment of the invention provides a display panel and a display device. The display panel comprises: a pixel definition layer disposed at one side of a substrate and comprising an isolation structure and a pixel opening formed by the isolation structure; and a first lens layer arranged on the side, away from the substrate, of the pixel definition layer, wherein the first micro lens layer comprises a first lens body and a lens opening defined by the first lens body, in the direction perpendicular to the substrate, the first lens body is at least overlapped with the isolation structure, the lens opening is overlapped with the pixel opening, the orthographic projection of the first lens body on the substrate is lens projection, the orthographic projection of the pixel opening on the substrate is pixel projection, and the distance d between the edge of at least part of the lens projection and the edge of the pixel projection is 0.

Description

technical field [0001] The present invention relates to the technical field of display devices, in particular to a display panel and a display device. Background technique [0002] Compared with liquid crystal displays, organic light-emitting displays have many advantages, such as thinner and thinner, higher brightness, lower power consumption, faster response, higher definition, better flexibility, and higher luminous efficiency, and have gradually become the mainstream display technology. The light-emitting principle of the organic light-emitting display is that the holes generated by the anode and the electrons generated by the cathode in the organic light-emitting device move under the action of an electric field, inject them into the hole transport layer and the electron transport layer respectively, and migrate to the organic light-emitting material. When the two meet in the light-emitting material layer, energy excitons are generated, thereby exciting the light-emitti...
