Abstract
A thin film transistor and its manufacturing method, an array substrate and a display device are disclosed, the thin film transistor is of a gate bottom contact type, and includes a gate electrode () and a gate insulation layer (), the gate insulation layer () is provided with a recess () at a position corresponding to the gate electrode (). With the thin film transistor, the problem of wire breakage in the active layer at the channel between the source/drain electrodes can be avoided, the performance and stability of the thin film transistor is improved, and the production cost is lowered down.
