PROBLEM TO BE SOLVED: To provide an LCD (Liquid Crystal Display) driving circuit for dynamically driving one LCD by first and second LCD drivers in such a manner that streak lines are not displayed at the boundary between first and second display elements display-driven by the first and second LCD drivers. SOLUTION: The LCD 300 is display-driven by the first LCD driver built in a microcomputer 100 and the second LCD driver 200 controlled by the microcomputer 100. Also, the LCD is provided with a switching circuit 400 which stops power supply to the second LCD driver 200. When a reset command is sent from the second LCD driver 200 to the LCD 300 and the microcomputer 100 is put into a sleep state after the display driving by the second driver 200 is stopped, the microcomputer 100 controls the switching circuit 400 to stop the power supply to the second LCD driver 200.
