Abstract

The invention discloses a display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. The manufacturing method of the display panel comprises the following steps: providing a substrate; forming an array layer on one side of the substrate; forming a light-emitting structure layer on one side, far away from the substrate, of the array layer, wherein the light-emitting structure layer comprises a plurality of light-emitting units; forming a shading layer on one side, far away from the substrate, of the light-emitting structure layer, wherein the shading layer comprises a black matrix and a plurality of openings; before the opening is formed, forming a first inorganic layer between the light emitting structure layer and the light shielding layer, wherein the first inorganic layer at least comprises a first sub-part, and the vertical projection of the first sub-part on the underlayer substrate is overlapped with the vertical projection of the opening on the underlayer substrate. The problem that in the prior art, large-area black photosensitive material residues exist in an opening area of a black matrix in a color filter, the subsequent manufacturing process of a color filter part is affected, and therefore the display quality of a display panel is affected is solved.

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] Organic Light Emission Diode (OLED) display, as a new generation of display device, has the advantages of thin and light, high contrast, fast response, wide viewing angle, high brightness, full color, etc. Assistants (PDAs), digital cameras, vehicle displays, notebook computers, wall-mounted TVs, and military fields have very broad application prospects. [0003] In order to reduce the reflectivity of external light in the organic light emitting diode display, one solution is to attach a circular polarizer to the light emitting surface of the organic light emitting diode display, but about half of the light emitted by the organic light emitting diode display will be absorbed by the circular polarizer, thus The light emitting effect of the organic light emitting ...
