<p>PURPOSE: A semiconductor device is provided to prevent the malfunction of a circuit by decreasing a drain current when a transistor is off. CONSTITUTION: A first transistor(111) supplies a first potential to a first wiring. A second transistor(112) supplies a second potential to the first wiring. A third transistor(113) supplies a third potential to the gate of the first transistor. A fourth transistor(114) supplies the second potential to the gate of the first transistor. A semiconductor device includes an offset voltage maintaining circuit.</p> |
