Abstract
In a drive circuit for driving a liquid crystal display element with a memory property, electric charges accumulated in a power-supply smoothing capacitor at the subsequent stage of a booster circuit are collected effectively after electricity is supplied to the liquid crystal display element. The drive circuit for driving the liquid crystal display element with a memory property supplies a boosted voltage to the driver circuit by turning on a first switch circuit while the liquid crystal display element is being reset or while an image is being rendered, and causing electric charges accumulated in the power-supply smoothing capacitor to be discharged while collecting them into a second battery by turning on a second switch circuit during a period in which electric charges accumulated in the power-supply smoothing capacitor should be discharged.
