Abstract
An optical phase difference component includes: a transparent base with a concave-convex pattern; gaps defined between convex portions of the concave-convex pattern; and a closing layer provided on the concave-convex pattern to connect the convex portions of the concave-convex pattern and to close the gaps. The phase difference property of the optical phase difference component is not reduced, even when the optical phase difference component is joined to another component with adhesive or when load is applied to the optical phase difference component.
