An optical modulation device comprises a first substrate having thereon a high-resistivity transparent conductor film and a plurality of low-resistivity conductor films disposed on the transparent conductor film and dividing the transparent conductor film into plural stripes; a second substrate having thereon a plurality of transparent conductor film stripes; and an optical modulation material, such as a ferroelectric liquid crystal, interposed between the first and second substrates. The optical modulation device further includes a plurality of connecting conductors for connecting with an external driver. The connecting conductors are disposed in a region free of the high-resistivity transparent conductor film of the first substrate and each connected to one of the low-resistivity conductor films.
