Abstract
A display apparatus including: a pixel section having a plurality of pixel circuits arranged two-dimensionally by being each provided at an intersection of a scan line and a signal line as a circuit including a switching device, a display element and a storage capacitor; and a correction circuit for correcting a storage-capacitor voltage supplied to the storage capacitors, wherein the correction circuit employs a comparator for detecting the difference between electric potentials received from a portion of the pixel section as a pixel electric potential having a positive polarity and a pixel electric potential having a negative polarity and for comparing the difference in electric potential with a reference voltage, and an output-voltage control circuit for converting a comparison result output by the comparator into a correction signal used for correcting the storage-capacitor voltage to be asserted on a storage-capacitor line used for supplying the storage-capacitor voltage.
