Claim Text:
1. A display device comprising: a substrate; a display element; a transistor as a drive element of the display element, and including a second semiconductor layer including an oxide semiconductor, a gate insulating film provided on a selected region in the second semiconductor layer, and a gate electrode provided on the gate insulating film in order of closeness to the substrate; and a holding capacitance element holding electric charge corresponding to a video signal, and including a first conductive film, a first semiconductor layer including an oxide semiconductor, an insulating film, and a second conductive film in order of closeness to the substrate, wherein, both the first conductive film and the second semiconductor layer come into direct surface contact with the substrate, wherein the display element, the transistor, and the holding capacitance element are provided on the substrate, wherein the first and second semiconductor layers are integrally formed of a same material on the substrate, wherein the second conductive film is formed of a same material as a material of the gate electrode, wherein the gate insulating film of the transistor and the insulating film of the holding capacitance element are separated from one another by a gap, and wherein the gate electrode is formed in a same element layer as the second conductive film.
