Embodiment Construction
[0059] In order to further illustrate the display substrate, the manufacturing method thereof, and the display device provided by the embodiments of the present invention, a detailed description will be given below in conjunction with the accompanying drawings.
[0060] Taking OLED display substrates with top emission structure as an example, such as figure 1 with Figure 2f As shown, the first transistor for outputting the driving signal includes: a semiconductor active layer 41, a conductive connection structure 42 located on both sides of the semiconductor active layer 41 and coupled with the semiconductor active layer 41, and a gate insulating layer 32 , the gate 50, the first insulating layer 33, the input electrode 61 and the output electrode 62. A light-shielding layer 20 and a conductive connection structure 42 are arranged between the output electrode 62 of the first transistor and the substrate 10, so that in the direction perpendicular to the substrate 10, the outp...
