Abstract

A liquid crystal prism element includes a pair of opposing substrates, a plurality of triangular prisms which have a ridge line extending in a Y axis direction and are arranged between the opposing substrates so as to be aligned along an X axis direction, and a liquid crystal layer formed between the opposing substrates. Each triangular prism has an inclined surface located on a center side of the opposing substrate in the X axis direction, an inclined surface located on a lateral side of the opposing substrate in the X axis direction, and a bottom surface. Both of the two inclined surfaces of a triangular prism provided at least in a portion of a region on the opposing substrate are formed so as to not be perpendicular to the opposing substrate.
