DISPLAY DEVICE, ARRAY SUBSTRATE, AND THIN FILM TRANSISTOR THEREOF

摘要

A thin film transistor is provided. In this thin film transistor, the thickness of the gate is increased. Therefore, the source and drain of this thin film transistor can be disposed on the side wall of the gate to decrease the occupied area of the thin film transistor. An array substrate and a display device using the thin film transistor are also provided.
