Thin film transistor, manufacturing method thereof, array substrate and display device

Abstract

The invention provides a thin film transistor, a manufacturing method thereof, an array substrate and a display device. Wherein, the active layer of the thin film transistor comprises a channel region, a first conductorized region and a second conductorized region, and the channel region is arranged between the first conductorized region and the second conductorized region, wherein the channel region comprises Opposite the first side and the second side, the first side is in contact with the third side of the first conductorization region, the second side is in contact with the fourth side of the second conductorization region, and the length of the first side is greater than the length of the first conductorization region The length of the three sides. The inventors have found that the thin film transistor has a simple structure, is easy to implement, has a high yield rate, and has a relatively uniform width of the channel region along the direction of the first side, so that the threshold voltage of the thin film transistor is relatively uniform, and the channel region is almost inert. The phenomenon of conductorization occurs.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a thin film transistor and a manufacturing method thereof, an array substrate and a display device. Background technique [0002] Thin film transistors have been widely used due to their advantages of simple fabrication process and small parasitic capacitance between the gate and the source and drain. However, in the current thin film transistor, due to the limitation of the manufacturing process, the design of the channel region of the thin film transistor can easily lead to the phenomenon of conduction in the channel region of the thin film transistor, and the product yield is low, thereby limiting its application. [0003] Therefore, the current thin film transistors still need to be improved. SUMMARY OF THE INVENTION [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. Therefore, an objec...
