Claim Text:
1. A lateral gate electrode TFT (Thin Film Transistor) switch, comprising: a substrate; a source-drain area which is disposed on the substrate and comprises a source electrode, a drain electrode and a semiconductor layer, the semiconductor layer being disposed between the source electrode and the drain electrode, the source electrode and the drain electrode being vertically disposed on the substrate; a gate insulation layer disposed adjacent to the source-drain area; a gate electrode disposed adjacent to the gate insulation layer, wherein the gate insulation layer is used to separate the source-drain area from the gate electrode, the semiconductor layer comprises a first ohm-contact layer, an active layer and a second ohm-contact layer, the active layer is disposed between the first ohm-contact layer and the second ohm-contact layer; and an insulation layer disposed between the source electrode and the semiconductor layer, a conductive channel is formed on a portion, without disposition of the insulation layer, between the source electrode and the semiconductor layer.
