Claim:
A display apparatus comprising: a pixel section having pixels arranged in a matrix; and a horizontal driving circuit and a vertical driving circuit configured to drive signal lines and scanning lines in the pixel section, whereby an image is displayed in the pixel section, wherein each pixel includes a light-emitting element, a signal-level-holding capacitor, a write transistor configured to be turned on and off by a write signal output from the vertical driving circuit, and configured to set a terminal voltage of the signal-level-holding capacitor to a signal level of one signal line, and a driving transistor having a gate and a source to which ends of the signal-level-holding capacitor are connected, the driving transistor being configured to cause the light-emitting element to emit light by driving the light-emitting element in accordance with a voltage across the gate and source of the driving transistor, wherein, in a threshold voltage correcting period in a non-emission period in which light emission by the light-emitting element is stopped, after the write signal turns on the write transistor to set potentials at ends of the signal-level-holding capacitor to predetermined potentials, a threshold voltage of the driving transistor is set in the signal-level-holding capacitor by discharging stored charge of the signal-level-holding capacitor through the driving transistor, wherein, in a mobility correcting period in the non-emission period in which the light emission by the light-emitting element is stopped, the mobility correcting period following the threshold voltage correcting period, after the write signal turns on the write transistor to set a voltage at one end of the signal-level-holding capacitor to the signal level of the one signal line, the driving transistor charges the other end of the signal-level-holding capacitor by turning on the driving transistor, wherein a fall of the write signal turns off the write transistor, and wherein the vertical driving circuit includes a threshold-voltage-correcting-period write-signal generating unit configured to generate the write signal in the threshold voltage correcting period, a mobility-correcting-period write-signal generating unit configured to generate the write signal in the mobility correcting period, and a selective output unit configured to selectively output, to the pixel, the write signal in the threshold voltage correcting period and the write signal in the mobility correcting period.
