Abstract
A light modulating device having a signal input unit for generating an optical signal, an optical switching unit using an alternately-laminated structure consisting of insulating layers sandwiching a conductive or semiconductive layer, and a display medium responsive to electric field. The device controls the electric field strength applied to the display medium by irradiating or interrupting light on the optical switching unit in accordance with an input signal, and performs a display corresponding to the input signal.
