Thin film transistor(TFT) which is of great importance in the properties of display devices is the key device of liquid crystal display. In this paper, the research history and the operating principles of TFT are described, meanwhile, the outstanding properties and recent research progress on thin film transistor such as amorphous silicon TFT, polycrystalline silicon TFT, organic TFT and ZnO-Based TFT are analyzed. At last, the development trends of thin film transistor are forecasted.
