PROBLEM TO BE SOLVED: To provide a semiconductor device having a small circuit size.SOLUTION: A semiconductor device comprises a first transistor, a second transistor and a capacitative element. A gate of the second transistor is electrically connected with either of a source or a drain of the first transistor. One of a pair of electrodes of the capacitative element is electrically connected with the gate of the second transistor. The other of the pair of the electrodes of the capacitative element is electrically connected with either of a source or a drain of the second transistor. When the first transistor is turned to an off state, the gate of the second transistor is turned to a floating state. A channel of the first transistor can be formed in an oxide semiconductor. |
