OPTICAL PHASE DIFFERENCE COMPONENT, COMPOSITE OPTICAL COMPONENT INCORPORATING OPTICAL PHASE DIFFERENCE COMPONENT, AND METHOD FOR MANUFACTURING OPTICAL PHASE DIFFERENCE COMPONENT

摘要

This optical phase difference component (100) comprises: a transparent base body (40) having a concavo-convex pattern (80); gaps (90) defined between convex portions (60) of the concavo-convex pattern (80); and a sealing layer (20) provided on the concavo-convex pattern (80) so that the convex portions (60) of the concavo-convex pattern (80) are connected and the gaps (90) are sealed. The phase difference properties of the optical phase difference component (100) do not degrade even when the optical phase difference component (100) is bonded to another component with an adhesive, or when a load is applied thereto.
