Claim 0:
1. A display substrate, comprising:
a base substrate;
a metal pattern located on the base substrate, and
an anti-reflection pattern located on a surface of the metal pattern proximate to the base substrate;
wherein a material of the anti-reflection pattern comprises molybdenum oxide doped with a refractory metal, and a melting point of the refractory metal is greater than a temperature threshold,
wherein the display substrate is an array substrate, and the metal pattern is a gate metal layer pattern,
wherein a material of the metal pattern is copper, the array substrate further comprises a source-drain metal layer pattern, and a material of the source-drain metal layer pattern is a stacked structure of molybdenum/aluminum/molybdenum structure,
wherein the refractory metal comprises tantalum, the thickness of the anti-reflection pattern is 54 nm, a thickness of the gate metal pattern is 350 nm, the source-drain metal layer pattern is a stacked structure of molybdenum/aluminum/molybdenum, and thicknesses of molybdenum, aluminum and molybdenum layers are 15 nm, 300 nm, and 80 nm, respectively, and
wherein in the anti-reflection pattern, a molar ratio of the refractory metal to molybdenum is in a range of 2:100 to 10:100.
