Abstract:
1. A thin film transistor, comprising: an active layer formed on an insulating substrate and having a channel region, a source region, and a drain region formed therein; a gate electrode formed over the channel region; a source electrode and a drain electrode respectively formed over the source region and the drain region, and electrically connected to the source region and the drain region, respectively; a body contact region formed in the active layer so that the body contact region is in contact with the channel region, and separated from the source region and the drain region by the channel region; and a connection having a contact wiring directly connected to both the body contact region and the source electrode or the drain electrode and formed between the body contact region and the source electrode or the drain electrode, such that a voltage is applicable to the channel region through the body contact region and to the source electrode or the drain electrode, wherein the body contact region is directly connected with the channel region and only connected with the channel region from among the source region, the drain region and the channel region in the active layer, and wherein the body contact region is physically connected to the source electrode or the drain electrode by the contact wiring.
