Problems solved by technology

[0003] However, in the production process of OLED devices, some manufacturing processes are cumbersome and the production efficiency of OLED devices may even affect the quality of products.
For example, the pixel definition layer, the traditional pixel definition layer is formed by one-time exposure and development technology, the technology itself is relatively cumbersome, and the etching process is easy to cause damage to the surface of the anode layer

Abstract

The embodiment of the invention discloses a manufacturing method of a display panel and the display panel. The manufacturing method of the display panel comprises: providing an array substrate; forming an anode layer on the array substrate; forming a first pixel defining layer on the array substrate and the anode layer, wherein the first pixel defining layer comprises a pixel opening for exposingthe anode layer; etching the first pixel defining layer to form a second pixel defining layer; forming a light-emitting layer covering the anode layer in the pixel opening area; forming a cathode layer on the light emitting layer; and forming a packaging layer covering the cathode layer, the second pixel defining layer and the array substrate. According to the scheme, the manufacturing process ofthe pixel defining layer can be simplified.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a method for manufacturing a display panel and the display panel. Background technique [0002] Organic Lighting Emitting Diode (OLED) devices have attracted widespread attention due to their advantages of self-luminescence, rich colors, fast response, wide viewing angle, light weight, and flexible display. [0003] However, in the manufacturing process of the OLED device, some manufacturing processes are cumbersome and the production efficiency of the OLED device is affected, and even the quality of the product is affected. For example, the pixel definition layer, the traditional pixel definition layer is formed by one-time exposure and development technology, which is relatively cumbersome, and the etching process is easy to cause damage to the surface of the anode layer. Contents of the invention [0004] Embodiments of the present application provide a method fo...
