Optical modulation device with masking structure and method of driving the same

摘要

An optical modulation device driven in a time-sharing manner comprises pluralities of signal and row electrodes oppositely spaced from each other, and a liquid crystal interposed between signal and row electrodes, wherein at least one of electrode the plates is provided with a metallic light shielding mask on an electrode provided in a section except for the section serving as a shutter opening, and in that a colored insulating film is provided between row electrodes.
