PURPOSE:To simplify the display section drive circuit, by opposingly providing two common electrodes and a plurality of segment electrodes via liquid crystal and setting the ratio of opposing area between each segment electrode and each common electrode to a given value. CONSTITUTION:A common electrode 2 is formed in step shape, and it has a given opposing area with segment electrodes 3-8 opposed each other. When pulses are fed to a 7-notation step down counter 10 from a time signal generating circuit 9 for a given period, e.g., every 10min, a counter 10 counts down sequentially by one step from the content of time set at a time set circuit 11, and the output transits to high potential sequentially according to each value. As a result, the display section corresponding to opposing areas 3a-8a of the segment electrodes 3-8, illuminates. |
