    摘要: An object of the invention is to provide a TFT substrate and a method for producing a TFT substrate which is capable of drastically reducing the production cost by decreasing the number of steps in the production process and improving production yield. A TFT substrate includes: a substrate; a gate electrode and a gate wire formed above the substrate; a gate insulating film formed above the gate electrode and the gate wire; a first oxide layer formed above the gate insulating film which is formed at least above the gate electrode; and a second oxide layer formed above the first oxide layer; wherein at least a pixel electrode is formed from the second oxide layer.

    摘要: Disclosed is a semiconductor thin film which can be formed at a relatively low temperature even on a flexible resin substrate. Since the semiconductor thin film is stable to visible light and has high device characteristics such as transistor characteristics, in the case where the semiconductor thin film is used as a switching device for driving a display, even when overlapped with a pixel part, the luminance of a display panel does not deteriorate. Specifically, a transparent semiconductor thin film 40 is produced by forming an amorphous film containing zinc oxide and indium oxide and then oxidizing the film so that the resulting film has a carrier density of 10+17 cm−3 or less, a Hall mobility of 2 cm2/V·sec or higher, and an energy band gap of 2.4 EV or more.
