METHOD AND DEVICE FOR LIQUID CRYSTAL DISPLAY

PURPOSE:To store and hold display contents right before abnormality occurs in a circuit of the device which displays characters, numbers, images, etc., on liquid crystal in case of the abnormality. CONSTITUTION:This device has a liquid crystal display element 18 which applies a voltage between electrodes 182 and 183 to produce an electric field, changes the molecule orientation of the liquid crystal 181 according to the direction of the electric field, and stores the molecule orientation, and an information monitor circuit 14 monitors a source voltage VDD to outputs a display stop signal when the voltage value varies out of a specific range; and a control circuit 15 performs OFF control over the voltage applied between the electrodes 182 and 183 according to the signal, thereby removing the electric field from the liquid crystal 181. Consequently, the molecule orientation of the liquid crystal 181 is held in the state before the applied voltage is brought under the OFF control.
