SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A substrate and a manufacturing method therefor, and a display device, which are used to solve the problem that an insulation layer (4) breaks when the insulation layer (4) is formed on an aluminum electrode (2) of a substrate (1). The substrate comprises an aluminum electrode (2) located on the substrate (1) and provided with a first set pattern, and further comprises an aluminum oxide layer or aluminum nitride layer (3) with a second set pattern, wherein the aluminum oxide layer or aluminum nitride layer (3) is disposed on the same layer as the aluminum electrode (2). The first set pattern and the second set pattern are complementary.
