Optical modulation device with pixels each having series connected electrode structure

An optical modulation device, comprising:

• a first substrate provided with a plurality of scanning signal lines, a plurality of data signal lines intersecting the scanning signal lines, a plurality of pixel electrodes each comprising a plurality of portions electrically independently of each other, and a plurality of switching elements;
• a second substrate provided with a plurality of counter electrodes confronting the pixel electrodes and electrically independent of each other, and
• an optical modulation substance disposed between the first and second substrates so as to form a plurality of pixels each provided with one switching element and each having an electrode structure wherein a respective portion of the optical modulation substance is sandwiched between a respective counter electrode and each portion of a corresponding pixel electrode so as to provide a plurality of capacitances connected in series as a load for each switching element, each of the plurality of capacitances being provided by a combination of each portion of the corresponding pixel electrode and the respective counter electrode sandwiching the respective portion of the optical modulation substance.
