Claim Text:
1. A display apparatus comprising: a plurality of pixels arrayed in a matrix along a row direction and a columnar direction; a plurality of semiconductor layers; a first insulation film provided above the plurality of semiconductor layers; a first conductive layer provided on the first insulation film and formed of metal; a second insulation film provided on the first insulation film and the first conductive layer; and a display element comprising a second conductive layer provided on the second insulation film; each of the plurality of pixels comprising: the display element connected between a high-potential power supply and a low-potential power supply; a drive transistor comprising a source electrode connected to the display element, a drain electrode connected to a reset line and a gate electrode; an output switch connected between the high-potential power supply and the drain electrode of the drive transistor, and configured to change a state between the high-potential power supply and the drain electrode of the drive transistor to a conductive state or a non-conductive state; a pixel switch connected between a video signal line and the gate electrode of the drive transistor, and configured to discriminate whether a signal provided via the video signal line is input to a side of the gate electrode of the drive transistor; and a holding capacitance connected between the source electrode and the gate electrode of the drive transistor; wherein the first conductive layer and the second conductive layer are opposed to each other to form a capacitance unit; and the drive transistor, the output switch, the pixel switch and the holding capacitance are formed by using the plurality of semiconductor layers.
