Title:
THIN FILM TRANSISTOR AND MANUFACTURING METHOD THEREFOR, DISPLAY SUBSTRATE, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/093171
Kind Code:
A1
Abstract:
Provided in the present disclosure are a thin film transistor and a manufacturing method therefor, a display substrate, and a display apparatus. The thin film transistor comprises: a gate electrode, an active layer, a source electrode and a drain electrode, which are arranged on a substrate, wherein the active layer is located on the side of the source electrode that is away from the substrate, the gate electrode is located on the side of the active layer that is away from the substrate, and the source electrode and the drain electrode are both connected to the active layer; a buffer layer, which is arranged between the active layer and the layer where the source electrode is located; a gate insulating layer, which is arranged between the active layer and the layer where the gate electrode is located, wherein the gate insulating layer is provided with a hollowed-out part; and an adapter electrode, which is located on the side of the active layer that is away from the substrate, one portion of the adapter electrode being electrically connected to the active layer by means of the hollowed-out part, and the other portion of the adapter electrode being electrically connected to the source electrode by means of a first via hole, wherein the first via hole penetrates at least the active layer and the buffer layer, and the orthographic projection of the first via hole on the substrate overlaps the orthographic projection of the hollowed-out part on the substrate.
