    摘要: A driving voltage generation device includes: a first selector section for receiving a plurality of first supply voltages and outputting one of the first supply voltages; a second selector section for receiving a plurality of second supply voltages and outputting one of the second supply voltages; first to fourth switches connected in series between the first selector section and the second selector section; a first specified voltage supply section for supplying a first specified voltage to a first interconnection node between the first switch and the second switch; and a second specified voltage supply section for supplying a second specified voltage to a second interconnection node between the third switch and the fourth switch. The first specified voltage supply section does not supply the first specified voltage when the first switch is on. The second specified voltage supply section does not supply the second specified voltage when the fourth switch is on. An output of the first specified voltage supply section has a lower impedance than that of the second selector section. An output of the second specified voltage supply section has a lower impedance than that of the first selector section.
