An optical shutter array is constituted by a first electrode that transmits three colors of light, a modulating layer that transmits the three colors of light transmitted through the first electrode, formed by a material of which the refractive index changes by application of voltage; and a second electrode constituted by a plurality of linear electrodes arranged in each of a plurality of divided regions, into which pixel portions have been divided, that transmit the three colors of light transmitted through the modulating layer. The first electrode, the modulating layer, and the second electrode are layered and provided between a pair of partially light transmitting mirrors. A configuration is adopted, in which the three colors of light transmitted through the linear electrodes are sequentially transmitted through the partially light transmitting mirror by sequentially switching and applying voltages to the linear electrodes.
