Abstract:
A liquid crystal device includes a liquid crystal panel, a pair of polarizers and a phase plate. The phase plate is formed by a supply direction of an inorganic material to the substrate surface set such that a ratio of a front phase difference, which is produced when light is incident along a normal direction of the phase plate, and a first phase difference, which is produced when light is incident along a first direction different from the normal direction, falls within a predetermined range.
