Abstract
A light emitting device including a pixel is provided. The pixel includes a light emitting element, a driving transistor connected to the light emitting element, a control transistor arranged between the driving transistor and a supply line and a write transistor arranged between a control terminal of the driving transistor and a signal line. One frame period includes a correction period during which the write transistor is rendered conductive and a reference signal is written in the control terminal, a write period during which the write transistor is rendered conductive and a luminance signal is written in the control terminal, and a light emission period. The control transistor is rendered conductive during a conductive state of the write transistor in the correction period, and is rendered conductive after the correction period and before the write period.
