Abstract
A display device for a display panel which is operated by both polarities of an applied voltage has a segment driving device connected to a segmental electrode of the display panel, a display controlling device connected to the power source, a resistive element connected between the segmental electrode and the display controlling device, and another resistive element connected between the display controlling device and the common electrode of the display panel. The voltage across the segmental electrode and the common electrode is provided by the segment driving device only when the display controlling device is in a short-circuited condition.
