Abstract

PURPOSE: To prevent charge from being accumulated in a liquid crystal cell by means of turning on/off a power source by supplying a selected potential to a corresponding gate bus in a liquid crystal panel for a prescribed time by means of all analog switches in a vertical scanning circuit when a detecting circuit detects the turned on/off state of the power source.
CONSTITUTION: When a detecting circuit 4 detects the turned on/off state of the power source, the selected potential is supplied by the respective analog switches in a vertical scanning circuit 2, and respective picture element transistors (TR) 13 connected to respective gate buses are all turned on. By inputting the potential equivalent to the potential of a facing common electrode instead of a video signal to a horizontal scanning circuit 3, the potential is supplied through respective drain buses D1 and D2 and the respective TRs 13 to the respective liquid crystal driving electrodes, and as a result, a voltage is not impressed to the respective liquid crystal cell 14. Thus by preventing the charge in the liquid crystal display panel from being accumulated at the time of turning on/off the power source, a baking phenomenon and a display deterioration such as a flicker are not generated even when the turning on/off operations of the power source are repeated.
