Abstract
An organic light-emitting diode array substrate and manufacturing method thereof are provided. The manufacturing method includes forming a semiconductor layer, a gate insulating layer, a gate, and a first insulating layer on a substrate; forming a first metal pattern on the first insulating layer, and the first metal pattern connecting to the gate through the through hole; forming a second insulating layer covering the first metal pattern on the first insulating layer; and forming a second metal pattern on the second insulating layer so that the second metal pattern and the first metal pattern overlap each other to form a capacitor.
