Abstract
A light signal generating device having a plurality of electro-optical light shutter elements which are turned on and off individually in accordance with image data. The light shutter elements are connected to individual electrodes each, and also connected to a common electrode. The common electrode and a power source for supplying a voltage to the individual electrodes are connected with a grounding line. Discharge lines are disposed between the common electrode and the grounding line, and switching elements are disposed on the discharge lines so as to prevent discharge currents, which are drawn from the light shutter elements at falls of the driving voltage, from flowing into the grounding line.
