Abstract

A thin film transistor includes a substrate, and a gate electrode, a gate insulating layer, an active layer, a source electrode and a drain electrode which are on the substrate. The active layer includes a channel region between the source electrode and the drain electrode and the channel region includes an edge region along a channel length direction and a main region outside the edge region. The thin film transistor further includes an auxiliary layer, a projection of the auxiliary layer on the substrate is at least partially overlapped with a projection of the edge region of the channel region on the substrate, and the auxiliary layer is configured to enhance a turn-on voltage of the edge region of the channel region.
