Abstract

The application discloses a thin film transistor, a manufacturing method thereof, an array substrate, and a display device, and belongs to the field of display technology. The thin film transistor includes: a gate pattern, a gate insulating layer, an active layer pattern, a source pattern, and a drain pattern stacked in sequence, the surface of the source pattern facing the gate insulating layer, the surface of the drain pattern facing the gate insulating layer, and Among the surfaces of the gate pattern facing the gate insulating layer, at least one surface is a target surface, and the target surface can diffusely reflect light incident on the target surface, so as to prevent part of the light from entering the active layer pattern. This application solves the problem that the volt-ampere characteristic curve of the active layer pattern will shift, which affects the normal operation of the thin film transistor, and weakens the influence of the target light on the normal operation of the thin film transistor. This application is used in a display device.

Description
