Abstract

One or more embodiments of the invention provide a display panel, a manufacturing method thereof and a display device. The display panel comprises a display area, an opening area and an isolation arealocated between the display area and the opening area. The method comprises the following steps: forming a source-drain electrode material film layer, forming a source-drain electrode layer in a display region through a composition process, and forming an isolation column transition pattern in an isolation region; and forming an undercut structure on the side wall of the isolation column transition pattern to generate an isolation column. According to the display panel, the manufacturing method of the display panel and the display device, the undercut structure on the isolation column is formed earlier than the anode layer, so that poor display caused by particles generated by silver precipitation due to replacement reaction between silver in the anode layer and aluminum in the isolationcolumn in the anode layer stripping process is reduced.

Description

technical field [0001] One or more embodiments of this specification relate to the field of display technology, and in particular, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of self-luminescence, fast response, wide viewing angle, high brightness, bright color, light and thin, etc., and is considered to be the next generation display technology. [0003] When some sensors such as a camera are placed in the screen, holes need to be made on the screen, and opening holes on the screen will easily expose the film layer of the OLED, so that the electro-luminescent layer (Electro-Luminescence, EL layer for short) ) form water and oxygen intrusion channels. At present, the isolation column is mainly used to block the EL layer, thereby blocking the water and oxygen intrusion channel. [0004] However, in the process of forming the display panel, when the anode layer ...
