Abstract: An optical device includes a first substrate having light transmission properties, a second substrate opposing the first substrate and having light transmission properties, and an optical control layer disposed between the first substrate and the second substrate and including a first light-transmitting portion that includes an optical medium and an uneven structure and a second light-transmitting portion that includes only the optical medium out of the optical medium and the uneven structure. The optical medium and the uneven structure have different refractive indices. In a plan view, the first light-transmitting portion and the second light-transmitting portion are repeatedly arranged in one direction, and the area of repetition of at least one of the first light-transmitting portion and the second light-transmitting portion varies in the one direction.

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.

Abstract: An optical device includes a first substrate which is light-transmissive, a second substrate which is light-transmissive and opposes the first substrate, a light distribution layer which is interposed between the first substrate and the second substrate and distributes incident light, and an optical element which is disposed on one of a surface of the second substrate on a side opposite to a side facing the first substrate and a surface of the first substrate on a side opposite to a side facing the second substrate. The light distribution layer includes an optical medium containing a birefringent material and an uneven structure. The optical element has an optical property of reducing an amount of at least one of first polarized light and second polarized light that differ in a polarization direction.

Abstract: An optical device includes a first optical adjuster, a second optical adjuster, and a phase modulation layer. The optical adjuster includes: an electrode; a counter electrode; a refractive index adjustment layer that has a refractive index changing in response to an electric field, is changeable between a transparent state and a state in which the refractive index adjustment layer distributes incident light, and has refractive index anisotropy; and a textured layer that gives the refractive index adjustment layer an uneven surface. The refractive index adjustment layer is provided between the electrode and the counter electrode and contains liquid crystals. The first optical adjuster and the second optical adjuster are arranged in the thickness direction of the optical device.
