Abstract

A display apparatus includes a plurality of pixels arranged in two-dimensions, each pixel including a pixel circuit and a light emitting element for emitting light at a luminance corresponding to a data signal, a data line, connected to each pixel circuit, for writing the data signal, and a light emitting period control signal line for supplying a light emitting period control signal. Each pixel circuit includes a light emitting element drive unit for supplying a current or voltage corresponding to the data signal to the light emitting element, and a light emitting period control unit for controlling a light emitting period of the light emitting element by the light emitting period control signal. The light emitting period control signals have two or more light emitting period control signals, and the respective pixels are divided into two or more groups by grouping the respective pixels disposed in a same row at least into a same group. Pixels in a same row are scanned in every other row and neighboring rows are sequentially scanned for writing the data signal, and the light emitting elements have an equal light emission duty and are controlled by the light emitting period control signal different on a group basis and controlled so that a time between an endpoint of a writing period within one field period and a start point of a light emitting period within the one field period is different for different groups.
