Display substrate, manufacturing method thereof, and display device

A display substrate, comprising:

• a base substrate;
• and
• a pixel unit disposed on the base substrate, wherein the pixel unit comprises a storage capacitor, the storage capacitor comprises a first plate and a second plate facing each other, and a plate of the storage capacitor is a transparent plate;
• wherein the pixel unit further comprises a light shielding layer, an active layer and a source/drain pattern, the light shielding layer is between the base substrate and the active layer, an orthographic projection of the active layer on the base substrate is within an orthographic projection of the light shielding layer on the base substrate;
• the light shielding layer comprises a transparent conductive thin film and a light-shielding conductive thin film which are superimposed, the transparent conductive thin film in the light shielding layer is closer to a side of the base substrate and is in direct contact with the base substrate, and an insulating layer is provided between the light shielding layer and the source/drain pattern;
• and
• the first plate comprises a first sub-plate, the first sub-plate comprises a transparent conductive thin film, the transparent conductive thin film of the first sub-plate is in direct contact with the insulating layer.
