Abstract

The invention provides a thin film transistor which comprises a grid electrode, a source electrode and a drain electrode arranged on a substrate and an active layer, the source electrode and the drainelectrode are electrically connected with the active layer, and at least one of the grid electrode, the source electrode and the drain electrode is a light absorption electrode. The light absorptionelectrode comprises an electrode body and a light absorption layer, the light absorption layer is arranged on one side, facing the active layer, of the electrode body. Correspondingly, the invention further provides a manufacturing method of the thin film transistor, an array substrate and a display device. The light irradiated on the active layer can be reduced, and the stability of the thin filmtransistor can be improved.

Description

technical field [0001] The invention relates to the field of semiconductor devices, in particular to a thin film transistor, a manufacturing method thereof, an array substrate and a display device. Background technique [0002] At present, amorphous silicon and low temperature polysilicon (LTPS) are widely used in semiconductor devices. However, most current silicon-based semiconductors are sensitive to light, and off-state currents are easily generated under light, which affects device stability. Contents of the invention [0003] The present invention aims to solve at least one of the technical problems existing in the prior art, and proposes a thin film transistor and its manufacturing method, an array substrate and a display device, so as to reduce the phenomenon that light hits the active layer and improve the stability of the thin film transistor. sex. [0004] In order to solve one of the above technical problems, the present invention provides a thin film transis...
