ABSTRACT:
An optical modulation element, in which a pixel surrounding a ferroelectric liquid crystal layer and an column shaped orientation layer is formed between a pair of electrodes. The orientation layer is formed by a high-molecular polymer in which an ultrafine granular conductive substance may be dispersed. External voltage applied across the electrodes in response to gradation signals performs gradation drivings.
