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

technical field [0001] The present application relates to the field of display technology, in particular to a thin film transistor and a manufacturing method thereof, an array substrate, and a display device. Background technique [0002] The array substrate in the display device includes: a base substrate and a plurality of pixel units arranged in an array arranged on one side of the base substrate, each pixel unit may include a thin film transistor, a pixel electrode, a common electrode and a liquid crystal. [0003] In related technologies, different voltages are usually input to pixel electrodes through thin film transistors, thereby changing the degree of deflection of liquid crystals, adjusting the light transmittance of pixel units, and then realizing the function of the display device to display images. Exemplarily, the thin film transistor may include: a gate pattern, a gate insulating layer, an active layer pattern, and a source-drain pattern stacked on the base su...
