Abstract
A TFT array substrate, its manufacturing method and a corresponding display device are disclosed. The TFT array substrate, includes a bearing substrate, a gate line and a data line arranged across each other on the bearing substrate, a pixel region defined by the gate line and the data line, and a thin film transistor, a pixel electrode and an active layer disposed in the pixel region. Specifically, a gate of the thin film transistor is connected to the gate line, a source thereof is connected to the data line and a drain thereof is connected to the pixel electrode. Further, an insulating layer is also formed above the source of the thin film transistor, and a drain trench is formed in the insulating layer. In addition, the drain of the thin film transistor is in the drain trench and is connected to the source through the active layer.
