PROBLEM TO BE SOLVED: To make it possible to suppress the increase in a circuit scale and power consumption associated with terminal multiplication. SOLUTION: Two or more levels of driving voltages corresponding to display data are outputted to a display means from a plurality of liquid crystal driving voltage output terminals 18 via a voltage follower circuit 21. A single voltage follower circuit 21 is connected with a plurality of the liquid crystal driving voltage output terminals 18 via an analog switch circuit 22, and is shared by a plurality of the liquid crystal driving voltage output terminals 18 by the change-over operation of the analog switch circuit 22.
