Abstract
A reflection type liquid crystal device has: a liquid crystal cell held between a pair of substrates and an optical compensation plate disposed outside the pair of substrates. The optical compensation plate has a first optical axis along the thickness direction thereof. The liquid crystal cell has a pretilt at which a second optical axis of a liquid crystal molecule of the liquid crystal cell is inclined with respect to a plate surface of the liquid crystal cell. The optical compensation plate is tiltable in a first direction in which a standard angle becomes larger, wherein the standard angle is defined as an acute angle between the first optical axis and the second optical axis when the optical compensation plate is located parallel to the plate surface of the liquid crystal cell.
