A multiple value voltage output circuit in which the number of transistors configuring a high breakdown voltage circuit portion can be reduced so that the area for forming the circuit is reduced. In a signal electrode driving circuit 11, an inverted AC-converting signal FRR inputted to switching control circuits 12 and 13 is selectively inputted to transistors 41 to 44 of an output buffer 14, on the basis of a data signal DA, thereby make one of the transistors 41 to 44 conduct so that a voltage corresponding to the turned-ON of the transistors 41 to 44 is outputted through an output terminal 15.
