Claim:
1. A thin film transistor (TFT) comprising: an active layer; a silicon oxide insulating layer arranged only at a lateral side of the active layer, wherein the active layer comprises ohm contact regions, the ohm contact regions are regions at two sides of the active layer, and the silicon oxide insulating layer surrounds an outer periphery of the ohm contact regions and the active layer; a gate electrode; a source electrode; a drain electrode; a gate insulating layer; and an interlayer insulating layer, the gate insulating layer being located on the active layer and covering both of the active layer and the silicon oxide insulating layer, the gate electrode being located on the gate insulating layer, the interlayer insulating layer being located on the gate electrode and covering the gate insulating layer, and the source electrode and the drain electrode being located on the interlayer insulating layer and in electrical connection with the active layer through via-holes in the interlayer insulating layer and the gate insulating layer.
