Zusammenfassung:	A liquid crystal panel drive device performs overdrive by using a frame memory ( 1 ) and a lookup table ( 2 ). The device is characterized by that there are provided a plurality of types of lookup table ( 2 ) to be used according to temperature and the lookup tables ( 2 ) are selectively switched from one to another according to the information indicating the ambient temperature. The device is configured so as to have a hysteretic characteristic when the tables are switched from one to another according to the temperature information.
