Abstract
According to the present invention, there is provided an organic thin film transistor array substrate and a method for manufacturing the same and a display device. The method for manufacturing the organic thin film transistor array substrate comprises: forming a pattern comprising a source electrode, a drain electrode, a data line and a pixel electrode on a transparent substrate through a first patterning process; forming an organic semiconductor pattern, a gate insulating layer pattern, a pattern comprising a gate electrode and a gate line through a second patterning process on the transparent substrate after the first patterning process; depositing a passivation layer on the transparent substrate after the second patterning process, and forming a pattern comprising a data line pad region, a gate line pad region and a pixel pad region through a third patterning process; and forming a pattern of a common electrode on the transparent substrate after the third patterning process through a fourth patterning process. The technical solutions of the present invention can increase production efficiency of the organic thin film transistor array substrate and reduce production costs.
