摘要:
A semiconductor device (1000) includes a thin film transistor having a gate line (3a), source and drain lines (13as, 13ad), and an island-like oxide semiconductor layer (7), and a capacitor element (105) having a first electrode (3b) formed from the same conductive film as the gate line (3s), a second electrode (13b) formed from the same conductive film as the source line (13as), and a dielectric layer positioned between the first electrode and the second electrode. A gate insulating film (5) has a layered structure including a first insulating layer (5A) containing an oxide and a second insulating layer (5B) disposed on the side closer to the gate electrode closer than the first insulating film and having a higher dielectric constant than the first insulating film, the layered structure being in contact with the oxide semiconductor layer (7). The dielectric layer includes the second insulating film (5B) but does not include the first insulating film (5A). Accordingly, the deterioration of the oxide semiconductor layer due to oxygen deficiency can be suppressed without reducing the capacitance value of the capacitor element).
