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.
