Abstract
In a CMOS circuit provided as part of a drive circuit in a frame region, a second TFT including a second semiconductor layer formed of an oxide semiconductor includes a first gate electrode provided on one surface side of the second semiconductor layer with a first inorganic insulating film interposed therebetween, and a second gate electrode provided on the other surface side of the second semiconductor layer with a second inorganic insulating film interposed therebetween. The second TFT is configured to apply a negative voltage to the second gate electrode during an off period in which no voltage is applied to the first gate electrode.
