Abstract

The present disclosure provides a thin film transistor (TFT), an array substrate, a display panel and a display device. The TFT includes a gate electrode, a gate insulating layer, a source electrode, a drain electrode and an active layer arranged on a base substrate, wherein there is a plurality of overlapping regions separated from each other where a projection of the gate electrode on the base substrate and a projection of the active layer on the base substrate overlap each other.
