Polarization separation device, manufacturing method thereof, and projection display device |
| abstract |
PROBLEM TO BE SOLVED: To provide a plate-like polarization separation device having a repeating structure in which a polarization separation film surface and a reflection film surface are alternately arranged at a fine pitch, and a projection type display using the polarization separation device. Provide equipment. In a manufacturing process of a polarization separation device, first, a glass block in which a plate glass having a polarization separation film formed of a multilayer film made of an inorganic material on the surface and a plate glass having a reflection surface on the surface are alternately stuck. The glass block is formed, and the glass block is cut along a cut surface oblique to the bonding surface. At least one of the side surfaces of the plate-shaped block thus cut out may be provided with a protrusion that can be used for positioning the polarization separation device. When a λ / 2 retardation plate is attached to a part of the light exit surface of the polarization separation device, the polarization separation that emits light from the light source unit as a light beam having one of s-polarization and p-polarization directions. A device is obtained. Such a polarization separation device can be used for a projection display device. |
