Abstract

See full text

The present invention provides a TFT substrate manufacturing method and a TFT substrate manufactured with the method. The TFT substrate manufacturing method of the present invention uses a photoresist pattern to serve as a shielding mask to allow a metal layer to be directly oxidized, through the anodic oxidation technology, into a gate insulation layer or a passivation layer, and at the same time, forming electrode patterns of gate or source/drain. The entire operation can be conducted in room temperature and is applicable to a flexible substrate that is not resistant to high temperatures without the involvement of expensive high temperature facility, such as chemical vapor deposition, so as to greatly reduce the operation cost of manufacturing a flexible display device. The TFT substrate manufactured with the present invention shows excellent electrical characteristics and is suitable for a flexible display device.
