Optical display device having a reflection-type polarizer |
摘要 |
A polarization device includes a reflection-type polarization element disposed at a side to which an optical beam comes in and an absorption-type polarization element disposed behind the reflection-type polarization element, wherein the reflection-type polarization element and the absorption-type polarization element are disposed such that a transmission axis of the reflection-type polarization element coincides with the transmission axis of the absorption-type polarization element. Further, an optical projector using such a polarization device is disclosed.
