Abstract

The invention provides a display substrate, a manufacturing method thereof and a display device. The display substrate comprises an underlayment substrate, and a source-drain metal layer, a flat layer and an electrode layer which are sequentially arranged from the side close to the underlayment substrate to the side far away from the underlayment substrate. The source-drain metal layer at least comprises a first source-drain metal pattern covered by the flat layer and a second source-drain metal pattern not covered by the flat layer. The electrode layer comprises an electrode pattern and a shielding pattern, and the electrode pattern is located on the flat layer. The shielding pattern directly covers at least part of the second source-drain metal pattern and is arranged along the pattern edge of the second source-drain metal pattern. According to the display substrate, the manufacturing method thereof and the display device provided by the embodiment of the invention, the technical problem of badness caused by side surface defects of the source-drain metal pattern when the electrode layer is etched can be solved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display substrate, a manufacturing method thereof, and a display device. Background technique [0002] In related technologies, the array substrate of a display panel includes a substrate, and a source-drain metal layer and an electrode layer on the substrate, and the source-drain metal layer includes a source electrode, a drain electrode, a data line, and each Source and drain metal patterns (such as terminals and traces of the bonding circuit, and packaging substrate patterns, etc.), the electrode layer is located on the side of the source and drain metal layer away from the substrate. [0003] When making an array substrate, firstly, a source-drain metal layer is formed on the substrate. The source-drain metal layer is made by patterning a metal layer, and the metal layer is usually made of titanium (Ti)-aluminum (Al)-titanium. Stacked structure; then, an insulatin...
