A digital circuit which can operate normally regardless of binary potentials of an input signal is provided. A semiconductor device comprising a correcting unit (301) and one or a plurality of circuit elements (302), the correcting unit including a first capacitor (303), a second capacitor (304), a first switch (305), and a second switch (306), wherein the first electrode of the first capacitor (303) is connected to an input terminal (IN), the supply of a first potential (VDD) to the second electrode of the first capacitor (303) is controlled by the first switch (305), the supply of a second potential (VSS) to the second electrode of the second capacitor (304) is controlled by the second switch (306), and a potential of the second electrode of the first capacitor (303) or a potential of the second electrode of the second capacitor (304) is supplied to the one or the plurality of circuit elements (302). <IMAGE> <IMAGE> <IMAGE>
