A display capable of suppressing the increase in current consumption is disclosed. The display comprises a first transistor connected to a first potential, a second transistor connected to a second potential, a third transistor for turning off the first transistor when the second transistor is in on state, a fourth transistor connected to the first potential, a fifth transistor connected to the second potential, and a sixth transistor operated to turn off when the third transistor is in on state and also operated to turn off the fourth transistor when the fifth transistor is in on state.
