摘要

PROBLEM TO BE SOLVED: To provide an optical element capable of performing precise driving at a low voltage while ensuring sufficient insulation performance.SOLUTION: The optical element includes: first and second electrodes disposed opposed to each other; an insulation film which has a dielectric layer and an ion barrier layer which are laminated in order to cover a face of the first electrode opposing to the second electrode; and polar liquid and nonpolar liquid sealed between the insulation film and the second electrode each of which has a refractive index different from each other. The dielectric layer has a permittivity higher than that of the ion barrier layer, the ion barrier layer prevents the ion included in the polar liquid from transmitting, and a water-repellent film is positioned at the uppermost layer of the insulation film and has an affinity with the nonpolar liquid.
