Abstract:
A thin-film transistor, comprising:a channel domain facing a gate electrode across a gate insulation film and a source/drain domain connected to the channel domain that are formed on a semiconductor film formed on the surface of a insulating substrate, said gate electrode and said channel domain being divided plurally in the channel-length direction; a low-concentration domain that is formed between the divided channel domains including a semiconductor film with a low impurity concentration; and a low-concentration drain domain having a low impurity concentration that adjoins the channel domain located closest to a drain-domain side among said divided channel domains, wherein the channel-length-direction dimensions of the gate electrode and the channel domain located in the drain domain side are shorter than in the channel-length-direction dimensions of the gate electrode and the channel domain located in the source domain side among said divided gate electrodes and channel domains.
