Abstract

An array substrate of an organic light-emitting display device, a fabrication method thereof and an organic light-emitting display device are provided. The array substrate comprises a plurality of pixel units arranged in array, wherein, at least one of the pixel units includes: an organic light-emitting diode () and a first thin film transistor () for controlling the organic light-emitting diode () which are formed on a base substrate (), wherein, the organic light-emitting diode () includes a first electrode (), a second electrode () and a light-emitting layer () located between the first electrode () and the second electrode (), the first electrode () of the organic light-emitting diode () being connected with a drain electrode () of the first thin film transistor (); and a conductive layer () and an insulating layer () formed between the first thin film transistor () and the organic light-emitting diode (), wherein, the first electrode () of the organic light-emitting diode (), the insulating layer () and the conductive layer () form a capacitor, and the conductive layer () is connected with a first gate electrode () of the first thin film transistor (). The array substrate of the organic light-emitting display device, the fabrication method thereof and the organic light-emitting display device can effectively increase a storage capacitance value of a pixel unit, so as to improve display quality.
