Disclosed herein is a display apparatus, including: a pixel array section including a plurality of pixels, a writing transistor, a driving transistor, a first switching transistor, a holding capacitor, and a second switching transistor; a first scanning section configured to drive the writing transistor in a unit of a row of the pixels; a second scanning section configured to drive the switching transistors in synchronism with scanning by the first scanning section; and a third scanning section configured to control the second switching transistors to a non-conducting state within a period after the image signal is written by the writing transistor until the signal writing period of the same row of the pixels ends but to a conducting state within any other period.

A display device employs first scan signals having a turn-on level that determines when pixels receive data voltages and second scan signals having a turn-on level that determines times for initializing anode voltages of light emitting elements in the pixels.

A blank period in the frame period is from when the pixels receive the last first scan signal at the last turn-on level to when the pixels receive an initial first scan signal of the turn-on level during a next frame period. The blank period is at least as long as a cycle in which each of the pixels receives the second scan signals at the turn-on level.
