Abstract: The present disclosure provides a pixel compensation circuit and a manufacturing method thereof, an OLED array substrate and a manufacturing method thereof, and a display device. The pixel compensation circuit includes a first TFT and a second TFT on a substrate. The first TFT includes: a first electrode on the substrate, a first interlayer dielectric layer on a side of the first electrode away from the substrate and having an opening exposing at least a portion of the first electrode; a second electrode on a side of the first interlayer dielectric layer away from the first electrode; and an active layer extending from the second electrode to the first electrode. The second TFT includes: an active layer on the substrate; and a first electrode and a second electrode in a same layer and on a side of the active layer of the second TFT away from the substrate.
