PROBLEM TO BE SOLVED: To improve persistently displayed screen quality by integrating the analog driving circuits of a liquid crystal display device and controlling these driving circuits by a control signal generated by a digital video signal processor and an EEPROM. SOLUTION: The driving circuit includes the analog driving circuit including a gamma circuit unit, a common circuit unit, and an inverter control unit, a digital analog converter unit for supplying the analog voltage necessary for driving of the analog driving circuit, a digital interface unit for supplying a digital signal to the digital analog converter unit, and a digital video processing unit for supplying the digital control signal to the digital interface unit.
