Abstract
An optical device () includes a first substrate () and a second substrate (), and an optical layer () interposed therebetween. The first substrate includes a first electrode () and a second electrode (), to which respectively different potentials can be applied. The optical layer () contains a medium (P) and anisotropically-shaped particles () whose alignment direction changes in accordance with the direction of an electric field applied to the optical layer. The medium is a liquid crystal material. When no electric field is applied to the optical layer, the anisotropically-shaped particles are aligned substantially vertically with respect to the substrate plane.
