Abstract

The present application discloses a display panel and a manufacturing method thereof. The manufacturing method includes: forming a device layer on a substrate; Covered by photoresist; coating according to the photoresist pattern, so that the exposed part and the photoresist part are covered with the corresponding film layer; peeling off the photoresist part and the film layer covering the photoresist part, and then forming the corresponding target film layer. The manufacturing method carries out the manufacturing of the film layer according to the sequence of yellow light, coating and stripping. Since no etching process is used, all the process layers used as the base will not be damaged by etching, and good interface contact can be ensured.

Description

technical field [0001] The present application relates to the field of display panels, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] At present, when manufacturing a display panel, an etching process is used in the process of making a film layer. However, etching will cause process problems such as etching damage or etching residue on other film layers of the display panel, which will affect product quality. Contents of the invention [0003] The main technical problem to be solved by this application is to provide a display panel and its manufacturing method. The manufacturing method carries out the production of the film layer according to the order of yellow light, coating, and stripping. Since the etching process is not used, all the process layers used as the base Neither will be damaged by etching, which can ensure good interfacial contact. [0004] In order to solve the above technical problems...
