Abstract
An optical device includes a first electrode, a second electrode, a refractive index adjustment layer, and a textured layer. The first electrode is light-transmissive. The second electrode is light-transmissive and electrically paired with the first electrode. The refractive index adjustment layer is provided between the first electrode and the second electrode and has a refractive index that is adjustable in an arbitrary wavelength band from the visible light range to the near-infrared range. The textured layer gives the refractive index adjustment layer an uneven surface and is in the form of a film. The refractive index adjustment layer is variable between a transparent state and a state of distributing incident light.
