PURPOSE: To announce the drop of the voltage of a power source while the characters displayed on a liquid crystal display body are held displayed in the event of the voltage drop of the above-mentioned power source by putting off a back light if the power-supply voltage is lower than a reference voltage.
CONSTITUTION: The voltage of a power source part 3 is detected by a power- supply voltage detecting part 5. The detected voltage and the reference voltage are compared by a control part 6. The power supply to the back light 1 from the power source part 3 is stopped by a power supply control part 4 if the voltage of the power source part 3 is lower than the reference voltage as a result of the comparison. The back light 1 is then put out and the drop of the power source part 3 is announced. The characters, etc., displayed on the liquid crystal display part 2 are, therefore, hardly visible but are held displayed. The drop of the voltage is announced in this way in the state of displaying the characters, etc., displayed on the liquid crystal display device. In addition, the power consumption after the voltage drop is reduced.
