摘要： PROBLEM TO BE SOLVED: To provide an optical element, such as high-accuracy retardation element where a thin film-like birefringent material is stuck and to provide its manufacturing method. SOLUTION: A very thin retardation plate 14 is held between a first substrate 11 and a second substrate 12 via adhesive layers 16, 17. In this case, a flat curved face 14d at a boundary between a 1st adhesive layer 16 and the retardation plate 14 and a flat curved face 14e at a boundary between a 2nd adhesive layer 17 and the retardation plate 14 cancel out each other, and consequently, production of refractive force as a lens can be prevented in the retardation plate 14. Thus the phenomenon that light passing through a phase optical element 10 of a flat-shape, as a whole, will condenses or disperses according to the refraction difference in a topological optical element 10 can be suppressed.

摘要： PROBLEM TO BE SOLVED: To provide a projector having excellent light resistance and heat resistance and long service life and capable of restraining a contrast decrease caused by the effect of return light arising in a liquid crystal panel or the like. SOLUTION: A first polarization element 42c is disposed in a position where it is rotated around x axis as viewed from a paper surface. This makes it possible for the liquid crystal panel 41c and the first polarization element 42c to be disposed so as not to be parallel to each other, while minimizing a change in the cyclic pitch width of a recessed-and-projecting structure of the first polarization element 42c with respect to incident light and a change in the shape of a multi-layer structure. Accordingly, the component of return light can be discharged to the outside of an optical path. COPYRIGHT: (C)2008,JPO&INPIT
