Embodiment Construction

[0058] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0059] As mentioned in the background art, organic light-emitting display screens have many advantages compared with liquid crystal display screens, 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...

Abstract

The present invention provides a display panel, and manufacturing method thereof and display device. In the process of manufacturing the display panel, after a mask plate and a substrate are aligned according to the preset deviation of the first direction and the second direction, the follow-up etching process is carried out, and finally the second opening of a first refraction layer and the first opening of a pixel definition layer are aligned, the number of the opposite offsets in the first direction and the second direction is within an allowable range, so that the situation that the display panel has visual angle optical differences in different directions is improved, the light emitting effect of the display panel is improved, and it is guaranteed that the display effect of the display panel is high.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, 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...
