Abstract:
A thin film transistor, a display substrate, manufacturing methods thereof, and a display device are provided. The manufacturing method for the thin film transistor includes: forming a light-shielding metal pattern and a source-drain metal layer pattern on a base substrate; forming a buffer layer including first and second via-holes; forming a source electrode connected with the light-shielding metal pattern via the first via-hole, a drain electrode connected with the source-drain metal layer pattern via the second via-hole, and an active layer, an orthographic projection of the light-shielding metal pattern on the substrate completely covering that of the active layer on the substrate and at least partially covering those of the source and drain electrodes on the substrate; and forming a gate insulation layer and a gate electrode, orthographic projections of the gate insulation layer and the gate electrode on the substrate being identical.

Claim (Index 5):
The method for manufacturing a thin film transistor according to  claim 1 , wherein forming the light-shielding metal pattern and the source-drain metal layer pattern on the base substrate comprises:\n depositing a metal layer on the base substrate by using a sputtering process or a thermal-evaporation process; and patterning the metal layer to simultaneously form the light-shielding metal pattern and the source-drain metal layer pattern, wherein the base substrate is a glass substrate or a quartz substrate, and the metal layer is formed of any one of Cu, Al, Ag, Mo, Cr, Nd, Ni, Mn, Ti, Ta, W, or any combination of Cu, Al, Ag, Mo, Cr, Nd, Ni, Mn, Ti, Ta, and W.
