Abstract: This invention provides a polarization conversion element that is highly resistant to the heat and light that result from increased brightness levels. In said polarization conversion element, inorganic half-wave plates provided selectively on the output surface of a polarizing beam-splitter array have obliquely deposited layers comprising a dielectric material and the side surfaces of said obliquely deposited layers are covered by protective films.
