Assignee: BEIJING BOE DISPLAY TECHNOLOGY CO., LTD.
Field: Optics (Instruments)
Classification: CPC G | IPC G

Claim 8:
9. A method for preparing a display substrate of claim 1, comprising:
providing a base substrate;
forming an anti-reflection layer on the base substrate using molybdenum oxide doped with a refractory metal, wherein a melting point of the refractory metal is greater than a temperature threshold;
forming a metal layer on the anti-reflection layer;
coating photoresist on the metal layer, and exposing and developing of the photoresist to form a photoresist pattern; and
etching the anti-reflection layer and the metal layer with an etching solution using the photoresist pattern as a mask plate, to form the anti-reflection pattern and the metal pattern.
