Display substrate, manufacturing method thereof and display device

A display substrate comprises a substrate body (101), the substrate body (101) comprises a display area (AA), and the display area (AA) comprises a plurality of pixel areas (P); the at least four conductive layers (102, 103, 104 and 105) are arranged in a stacked mode and located on the substrate (101), any two adjacent conductive layers are arranged in a mutually insulated mode, each conductive layer (102, 103, 104 and 105) comprises conductive patterns located in the corresponding pixel area (P), the conductive patterns, in the same pixel area (P), of any two adjacent conductive layers form a storage capacitor (such as Cst1, Cst2 and Cst3), and in the direction perpendicular to the substrate (101), the storage capacitor (such as Cst1, Cst2 and Cst3) forms a storage capacitor (such as Cst1, Cst2 and Cst3). The projections of the at least four conductive layers (102, 103, 104 and 105) on the substrate (101) are overlapped. The invention further provides a manufacturing method of the display substrate and a di
