摘要： A display device with a compensation circuit that applies a fixed potential constantly to a gate electrode of a driving transistor for a certain period is provided. Specifically, each difference voltage value between an anode and a cathode of the light emitting element is utilized in the case where the light emitting element emits light and emits no light. In a case where the light emitting element emits light, a potential of the gate electrode of the driving transistor is to be held; and in a case where the light emitting element emits no light, a potential that certainly turns off the gate electrode of the driving transistor is kept on applying to the gate electrode of the driving transistor.
