To provide a liquid crystal device capable of improving a decrease with elapse of time in a conventional driving margin.

Driving means 102, 103 drive a liquid crystal which maintains a display state at the time of turning off a power supply even after signals are impressed on the electrodes according to display information and the power supply is switched off, and also display information generated by a display information generating part 109 or specific display information are inputted to these driving means 102, 103. Moreover, a control part 105 inputs detection information of a detecting means 106 for detecting power-supply-off to a display information generating part 109, and controls the display information generating part 109 to generate specific display information at the time of turning off the power supply. And, this liquid crystal device is arranged so that the liquid crystal maintains the state according to this specific display information even after the power source supply is turned off, by impressing the signal in accordance with the specific display information on the electrodes at the time of turning off the power supply in this manner for driving the liquid crystal.
