Abstract

The invention provides a display panel preparation method and a display device. The Display panel preparation method comprises the following steps: providing a substrate; and forming a barrier layer on the substrate; an electrode layer being on the barrier layer; forming a photoresist layer on the electrode layer; forming a protective layer on the substrate, wherein the protective layer covers thebarrier layer and the exposed surface of the electrode layer; stripping the photoresist layer by using a stripping solution; and removing the protective layer.

Description

technical field [0001] The invention relates to the field of display equipment, in particular to a method for preparing a display panel and a display device. Background technique [0002] In the existing display panel technology, because copper and other metals use photoresist (Photoresistance, PR) in the process of metal patterning, metal corrosion will occur in the subsequent photoresist stripping process, and metal corrosion will lead to metal hollowing out. Phenomenon. For example, copper hollowing will form metal tips, and different layers of metals are prone to electrostatic (ElectroStatic Discharge, ESD) breakdown in the subsequent manufacturing process, which has a great impact on product yield. After patterning copper and other metals, it is necessary to use a photoresist stripping solution to remove the remaining photoresist, and the photoresist stripping solution contains organic substances with amine groups, and the organic substances with amine groups dissociat...
