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.
