Abstract:
A light emitting device including a light emitting element, a driving transistor connected to the light emitting element and configured to supply a current corresponding to a signal, a light emission control transistor arranged between the driving transistor and a potential supply line and configured to control emission or non-emission of the light emitting element, a write transistor configured to supply the signal to the driving transistor, is provided. One frame period includes a write period during which the write transistor is rendered conductive and the signal is written, and a light emission period during which the light emission control transistor changes from a non-conductive state to a conductive state and the light emitting element emits light. After a start of the write period and before an end of the write period, the light emission control transistor is rendered conductive.
