Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a voltage generator circuit for supplying a plurality of voltages for use in gamma compensation of a video signal. SOLUTION: Reference voltages are input into an input electrode inputting first and second voltages. A voltage between the above reference voltages is divided by an input voltage dividing circuit consisting of a resistance potential divider circuit. The first voltage is a maximum input voltage, while the second voltage is a minimum input voltage. By an output voltage selection circuit, division voltages are selected according to a plurality of control signals to be output. COPYRIGHT: (C)2009,JPO&INPIT
