Abstract

Embodiments of the invention provide a thin film transistor and a manufacturing method thereof, a display panel and a display apparatus, relate to the technical field of display, and can lower the structural defect density of the thin film transistor and improve electrical characteristic of the thin film transistor. The thin film transistor comprises an active layer, a first insulating layer, a gate, a second insulating layer, a source and a drain, wherein the active layer comprises a first semiconductor layer and a second semiconductor layer; the first semiconductor layer comprises a plurality of first island-shaped structures which are arranged at intervals; the second semiconductor layer covers the first semiconductor layer and the gaps among the multiple first island-shaped structures;the source is connected to the active layer through source via holes in the first insulating layer and the second insulating layer; and the drain is connected to the active layer through drain via holes in the first insulating layer and the second insulating layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor, a manufacturing method thereof, a display panel and a display device. Background technique [0002] In the display panel, a thin film transistor is provided to realize the control function during the display process. If the electrical characteristics of the thin film transistor are poor, it may cause adverse effects on the display. During the manufacturing process of the current thin film transistor, the structural defect density of the thin film transistor will be increased, thereby reducing the electrical characteristics of the thin film transistor. Contents of the invention [0003] The invention provides a thin film transistor and its manufacturing method, a display panel and a display device, which can reduce the structural defect density of the thin film transistor, thereby improving the electrical characteristics of the thin film transistor.
