<p>A memory-type liquid crystal driving circuit wherein the charge stored in a power supply smoothing capacitor provided in a stage following a booster circuit can effectively be recovered after a termination of power supply to a liquid crystal display device. In the memory-type liquid crystal driving circuit: at a time of resetting or rendering of the liquid crystal display device (109), a first switch circuit (105) is turned on, thereby supplying a boosted voltage (VDDH) to driver circuits (107, 108); and when the charge stored in the power supply smoothing capacitor (104) is to be discharged, a second switch circuit (110) is turned on, thereby causing the charge stored in the power supply smoothing capacitor (104) to be discharged and thereby recovered into the second battery (112).</p> |
