Claim:
1. A thin film transistor on a polymer substrate, comprising: a gate electrode; a gate insulating film covered by the gate electrode, the gate insulating film comprising methylsiloxane having a methyl content in the range of from ≧1 wt.-% to ≦13 wt.-%; a semiconductor channel layer placed to face the gate electrode with the gate insulating film interposed there between, the semiconductor channel layer comprising at least one of a metal oxide semiconductor including an oxide of at least one of Hf, In, Ga, or Zn and mixtures thereof; a source drain pattern comprising a source electrode connected to the semiconductor layer and a drain electrode separated from the source electrode and connected to the semiconductor layer, wherein the semiconductor layer has a source portion that contacts the source electrode, a drain portion that contacts the drain electrode, and a channel portion that is located between the source and drain portions; wherein the gate electrode and the source and gate electrodes comprise at least one of Al, Ti, Mo, AlNd, a stack metal electrode Ti/Al/Ti, or a transparent conducting oxide selected from the group consisting of indium tin oxide, indium doped zinc oxide, aluminum doped zinc oxide, fluorine tin oxide, antimony tin oxide, and mixtures thereof; a polymer substrate comprising a thermoplastic polymer film.
