Patent ID: 8759823

Claim:
A fabricating method of an array substrate, comprising: forming a conductive material on a substrate and forming source and drain electrodes by etching the conductive material in a pixel region on the substrate; forming an organic semiconductor layer and a gate insulating layer on the substrate including the source and drain electrodes, forming a photosensitive organic material layer on the gate insulating layer, forming the organic semiconductor layer into an island shape that contacts facing ends of the source and drain electrodes by etching the organic semiconductor layer and the gate insulating layer, the gate insulating layer having the island shape; forming a first passivation layer on the gate insulating layer over all of a display area of the substrate; forming a gate electrode on the first passivation layer in the pixel region, the gate electrode corresponding to the gate insulating layer, wherein a portion of the first passivation layer is disposed between the gate insulating layer and the gate electrode and is in direct contact with an entire top surface of the gate insulating layer; forming a second passivation layer on the gate electrode all over the display area, the second passivation layer having a drain contact hole exposing the drain electrode; and forming a pixel electrode on the second passivation layer, the pixel electrode contacting the drain electrode through the drain contact hole.
