Abstract
An optical modulation device is constituted by a first substrate provided with a plurality of first electrodes each comprising a plurality of portions electrically independent of each other, a second substrate disposed opposite to the first substrate and provided with a plurality of second electrodes each confronting a corresponding first electrode, and an optical modulation substance disposed between the first and second substrates so as to form a plurality of pixels each having a particular electrode structure. In the electrode structure, the optical modulation substance is sandwiched between each second electrode and said portions of said corresponding first electrode so as to form a series circuit providing a plurality of capacitance, thus reducing the capacitance for each pixel to improve a switching characteristic while minimizing a defective portion due to a short-circuit between the confronting electrodes.
