Abstract
To provide an optical element capable of stably securing an intermediate mode between two operations modes. The optical element of the present invention includes: a first transparent substrate; a second transparent substrate provided by opposing to the first transparent substrate; a plurality of first conductive patterns and second conductive patterns disposed in parallel to each other on a face of the first transparent substrate opposing to the second transparent substrate; light transmission regions disposed between the first conductive patterns and the second conductive patterns; a transparent conductive film disposed on a face of the second transparent substrate opposing to the first transparent substrate; and an electrophoretic element disposed between the neighboring light transmission regions, which is constituted with light-shielding electrophoretic particles of a specific electric charge and a transmissive dispersion material.
