Provided is a shift register unit, a gate driving apparatus and a display device capable of increasing a lifespan of a shift register. The shift register unit according to the present disclosure includes: a first thin film field effect transistor, a drain thereof connected with a first signal terminal, a source thereof connected with the outputting node at the present stage, a gate thereof connected with a first node; a second thin film field effect transistor, a drain thereof connected with the first signal terminal, a source thereof connected with the pulling-up node, and a gate thereof connected with the first node; a third thin film field effect transistor, a drain thereof connected with a second signal terminal, a source thereof connected with the outputting node at the present stage, and a gate thereof connected with a second node; a fourth thin film field effect transistor, a drain thereof connected with the second signal terminal, a source thereof connected with the pulling-up node, and a gate thereof connected with the second node; and a node voltage control module, configured to control the first node and the second node to be in a high potential state alternatively when the shift register unit is in a pulling-down phase. The present disclosure increases the lifespan of the shift register.

Shift register unit, gate driving apparatus and display device

A thin film transistor and a method of manufacturing the same, an array substrate and a display device are provided, the thin film transistor including: a source, a drain, and a gate; and a semiconductor active layer, wherein the source overlays a periphery of the semiconductor active layer, the drain is located in a central region of the semiconductor active layer, and an insulation layer is disposed between the source and the drain. By means of the above thin film transistor, the ratio of width to length of a channel can be increased without influencing the aperture ratio of pixel.
