Abstract:
1. A display apparatus comprising: a pixel section having a plurality of pixel circuits arranged two-dimensionally, each pixel circuit being provided at an intersection of a scan line and a signal line and including a switching device, a display element and a storage capacitor; and a correction circuit configured to correct a storage-capacitor voltage supplied to said storage capacitors, said correction circuit comprising (a) a capacitor that has a first electrode and a second electrode, (b) a voltage comparison device that has a first input terminal, a second input terminal, and an output terminal, the first input terminal being connected to the second electrode of said capacitor, the second input terminal being supplied with a reference voltage, (c) a first switch that is connected to the first electrode of said capacitor and supplied with a pixel electric potential having a positive polarity, (d) a second switch that is connected to the first electrode of said capacitor and supplied with a pixel electric potential having a negative polarity, (e) a third switch that is connected between ground and a connection point between the second electrode of said capacitor and the first input terminal of said voltage comparison device, and (f) an output-voltage control circuit, wherein,
