Abstract
A thin-film transistor includes a metal electrode and a zinc oxide-based barrier film that blocks a material from diffusing out of the metal electrode. The zinc oxide-based barrier film is made of zinc oxide doped with indium oxide, the content of the indium oxide ranging, by weight, 1 to 50 percent of the zinc oxide-based barrier film. A zinc oxide-based sputtering target for deposition of a barrier film of a thin-film transistor is made of zinc oxide doped with indium oxide, the content of the indium oxide ranging, by weight, 1 to 50 percent of the zinc oxide-based sputtering target.
