Abstract: Provided are a thin film transistor and method for manufacturing the same, array substrate, display panel and display device. The thin film transistor includes: a gate pattern, a gate insulating layer, an active layer pattern, a source pattern and a drain pattern sequentially stacked. At least one of a surface of the source pattern facing the gate insulating layer, a surface of the drain pattern facing the gate insulating layer, and a surface of the gate pattern facing the gate insulating layer is a target surface which can diffusely reflect lights entering the target surface, to prevent part of the lights from entering the active layer pattern. The display device solves the problem of volt-ampere characteristic curve of the active layer pattern being deflected and a normal operation of the thin film transistor being affected, thereby weakening the influence of lights on the normal operation of the thin film transistor.

Abstract: Disclosed are a shift register unit and a method for driving the same, a gate drive circuit, and a display device. The pull-down control circuit in the shift register unit is capable of controlling a potential of a second pull-up node under control of the input signal provided by an input signal terminal. The pull-down circuit is capable of performing noise reduction on a first pull-up node and an output terminal under control of the second pull-up node. Since the potential of the second pull-up node is not pulled up due to the bootstrap effect, the threshold voltages of transistors in the pull-down circuit are less shifted, and the service life of the shift register unit is relatively long.
