Abstract

The invention provides a display substrate, a manufacturing method thereof and a display device. The manufacturing method of the display substrate comprises the steps that an insulation film layer isformed on a substrate base plate, and a via hole penetrating through the insulation film layer is formed; a conductive pattern is formed, wherein the conductive pattern includes, at least, a first conductive pattern covering the via hole and the edge of the via hole, and the first conductive pattern is made from a flexible conductive material. In the embodiment of the invention, the flexible conductive material is adopted to replace a traditional hard conductive material, the first conductive pattern covering the via hole and the edge of the via hole is formed, the first conductive pattern made from the flexible conductive material has higher flexibility, breakage is not likely to occur at the via hole, and the reliability of the display substrate is improved.

Description

technical field [0001] The 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 current Thin Film Transistor-Liquid Crystal Display (TFT-LCD) products, in order to ensure the charging rate of the product, the thickness of the passivation (PVX) layer will be increased to reduce the storage capacitance, but this will also increase A related problem is caused, that is, the step difference at the edge of the via hole on the passivation layer will be relatively large, and the conductive pattern used for connection is prone to breakage (Open) at the edge of the via hole, resulting in abnormal resistance at the via hole, resulting in pixel Display bad problems such as dark spots. [0003] With the development of TFT-LCD technology, the types of via holes are becoming more and more abundant. To solve the problem that the conductive patterns at the edge of th...
