Abstract
It is an object to provide a logic circuit which can be operated even when unipolar transistors are used. A logic circuit includes a source follower circuit and a logic circuit an input portion of which is connected to an output portion of the source follower circuit and all transistors are unipolar transistors. A potential of a wiring for supplying a low potential connected to the source follower circuit is lower than a potential of a wiring for supplying a low potential connected to the logic circuit which includes unipolar transistors. In this manner, a logic circuit which can be operated even with unipolar depletion transistors can be provided.
