Provided are a drive circuit substrate that requires few manufacturing steps and that achieves improved use efficiency of materials, a manufacturing method therefor, a display device, and an electronic device. This display device is provided with: a pair of source/drain electrodes; an organic semiconductor layer that forms a channel region and that is provided so as to be in contact with the source/drain electrodes; an insulating layer that has a through hole penetrating to the source/drain electrodes, and that is formed from at least one layer provided on the organic semiconductor layer and the source/drain electrodes; a gate electrode that is provided at a position corresponding to the channel region; and a pixel electrode that is provided on the insulating layer, electrically connected to the source/drain electrodes via the through hole, made from the same material as the gate electrode, and has the same film thickness as the gate electrode.
