Abstract
A light emitting device is provided. The device includes a plurality of pixels, each pixel including a light emitting element and a driving transistor configured to supply a current corresponding to a luminance signal to the light emitting element and a driving circuit including a scanning circuit configured to perform write scanning of scanning the plurality of pixels on a row basis and writing the luminance signal in a gate of the driving transistor. The driving circuit performs, only during a period from an activation of the light emitting device to a start of the write scanning when the write scanning is performed for a first time, a signal write operation of collectively writing a predetermined signal in the gates of the driving transistors included in pixels arranged in not less than two rows among the plurality of pixels.
