Abstract
A liquid crystal device includes a first substrate that is arranged on a light input side; a second substrate that is arranged on a light output side; a liquid crystal layer that is arranged between the first and second substrates; a first microlens that is provided on the first substrate such that an optical axis is tilted to a normal line direction of the first substrate; and a second microlens that is provided on the second substrate such that an optical axis is tilted to a normal line direction of the second substrate, in which a focal point of the first microlens is located on a curved surface of the second microlens, or on the light output side rather than the curved surface.
