Claim Text:
1. A manufacturing method of an organic this film transistor (OTFT) array substrate, comprising: depositing a gate metal thin film, a gate insulating layer thin film and an organic semiconductor thin film on a transparent substrate sequentially, and forming a pattern including a gate electrode, a gate insulating layer and an active layer of an OTFT which are uniform in shape and a gate line through a first patterning process; forming a passivation layer thin film on the transparent substrate subjected to the first patterning process, and forming a pattern of a first passivation layer unit and a second passivation layer unit through a second patterning process; depositing a transparent conductive thin film and a source-drain metal thin film sequentially on the transparent substrate subjected to the second patterning process, and through a third patterning process, forming a pattern of a source electrode and a drain electrode of the OTFT and a data line with the source-drain metal thin film, and forming a pattern of a first contact layer unit under the source electrode of the OTFT, a second contact layer unit under the drain electrode of the OTFT, a third contact layer unit under the data line and a pixel electrode which is directly connected to the second contact layer unit with the transparent conductive thin film; wherein, on a channel region of the active layer of the OTFT, there is provided the first passivation layer unit; wherein the second passivation layer unit at least covers edges of the gate electrode, the gate insulating layer and the active layer of the OTFT which are uniform in shape and is in contact with a top surface of the active layer at edges of the active layer.
