ABSTRACT:
A first resistor string provides a plurality of first polarity gamma-reference-voltages. A second resistor string provides a plurality of second polarity gamma-reference-voltages. A first main-thermal compensation section exhibits a resistance value that increases with an increase of temperature. A second main-thermal compensation section has a resistance value that is decreases with an increase of temperature. Thus, gamma-reference-voltages corresponding to white gradation are decreased and gamma-reference-voltages corresponding to black gradation are maintained, so that a deviation of kickback voltage corresponding to the white gradation is decreased.
