==Original Abstract Submitted==

A light emitting device including a pixel that includes a current path including a light emitting element and a driving transistor is provided. The pixel further includes a first switching transistor arranged between the path and a first power line, a second switching transistor arranged between the path and a second power line, and a write transistor to write a luminance signal in the gate. A potential of the first power line is lower than that of the second power line. One frame period includes a write period in which the write transistor is rendered conductive to write the luminance signal, and a light emission period. In the write period, the second switching transistor is rendered conductive while the write transistor is rendered conductive, and in the light emission period, the first switching transistor is rendered conductive.
