Liquid crystal optical element and image display apparatus including the same
First Claim
1. A liquid crystal optical element comprising:
- a first prism array;
a second prism array arranged so as to face the first prism array; and
a liquid crystal layer provided between the first and second prism arrays, whereinthe first prism array is composed of a plurality of first prisms that have ridge lines extending in a first direction and are arranged so as to be spaced apart from each other at predetermined intervals in a second direction perpendicular to the first direction,the second prism array is composed of a plurality of second prisms that have ridge lines extending in the first direction and are arranged so as to be spaced apart from each other at predetermined intervals in the second direction,each of the first prisms has a first inclined outer surface facing a center plane that is perpendicular to the second direction and passes through a center line of the liquid crystal optical element, andeach of the second prisms has a second inclined outer surface facing the center plane.

Abstract
A liquid crystal prism element includes: a first prism array; a second prism array arranged so as to face the first prism array; and a liquid crystal layer provided between the first and second prism arrays. The first prism array is composed of a plurality of first prisms that have ridge lines extending in a Y axis direction and are arranged so as to be spaced apart from each other at predetermined intervals in an X axis direction The second prism array is composed of second prisms that have ridge lines extending in the Y axis direction and are arranged so as to be spaced apart from each other at predetermined intervals in the X axis direction. Each first prism has an inclined surface facing a center side of the liquid crystal layer. Each second prism has an inclined surface facing the center side of the liquid crystal layer.
