Abstract
A display device which is driven by a high driving voltage, has a display panel with display electrodes. A conductor line extends along the surface of the display panel. A high voltage producing means is connected to one end of the conductor line for applying a high voltage to the display electrodes. A low voltage source is connected to the other end of the conductor line for operating the high voltage producing means. Thus, an application of the high voltage to the display electrodes is terminated when the conductor line is broken or cut as a result of damage to the display panel.
