| titleOfInvention | Polarized light separator, method of manufacturing the same, and projection display |
| abstract | According to the present invention, there is provided a plate-shaped polarization splitting device having a repeating structure in which the polarization splitting film surface and the reflective film surface are alternately arranged at a fine pitch, and a projection display device using the polarization splitting device. In the manufacturing process of the polarization splitting apparatus, first, a glass block having a plate glass having a polarizing separation film composed of a multilayer film made of an inorganic material on the surface and a plate glass having a reflecting surface on the surface are formed and inclined with respect to the attachment surface. Cut the glass block along the cut surface of the In this way, at least one side of the cut plate-shaped block is provided with a projection used for positioning the polarization splitting apparatus. When the lambda / 2 phase plate is attached to a part of the light exit surface of the polarization splitting device, a polarization splitting device which emits light from the light source unit as a light beam having a polarization direction on either side of S polarization or P polarization is obtained. In this manner, the polarization splitting device can be used for a projection display device. |
