Fabrication method for an organic thin film transistor substrate

摘要

An organic thin film transistor (TFT) substrate with a simplified fabrication process is disclosed. The TFT substrate includes a gate line and a data line and an organic TFT connected to the gate line and the data line. The gate line and the data line define a pixel region where a pixel electrode is formed. A first contact portion connects the data line to the organic TFT, and a second contact portion connects the pixel electrode to the organic TFT. A passivation layer covers the organic TFT. The organic TFT substrate also includes a bank insulating layer with a first contact hole for connecting the first contact portion to the organic TFT, a second contact hole for connecting the second contact portion to the organic TFT, a first sub bank defining a location of the gate insulating layer, and a second sub bank defining a location of the passivation layer.
