Zusammenfassung:PROBLEM TO BE SOLVED: To provide a display device including a thin-film transistor for acquiring appropriate ON current and OFF current, and a method of manufacturing the display device. SOLUTION: The display device includes: a gate electrode GT stacked over a transparent substrate GA; a source electrode ST and drain electrode DT stacked over it; a first semiconductor film S stacked between them and controls the current between the source electrode ST and drain electrode DT; an insulating film ES that exposes a source-side end SR and a drain-side end DR of the first semiconductor film S and is stacked in contact with the upside of the first semiconductor film S; and a second semiconductor film AS and third semiconductor film DS stacked both between the source-side end SR and source electrode ST and between the drain-side end DR and drain electrode DT. The third semiconductor film DS is in ohmic contact with the source electrode ST and drain electrode DT, and the second semiconductor film AS is formed under the third semiconductor film DS so as to have a resistance higher than that of the third semiconductor film DS.
