Polarizing device and projector |
摘要 |
A polarizing device includes: a first prism substantially formed in a triangular shape; a second prism substantially formed in a triangular shape and bonded to the first prism; and a polarization splitter film provided at a bonding surface at which the first prism and the second prism are bonded to each other. A shape of a section of the first prism is determined so as to allow an optical axis of light having entered through one surface of the first prism to enter the polarization splitter film with an angle of incidence smaller than 45°.
