L1.3: Late-News Paper: PS Polarization Converting Device for LC Projector Using Holographic Polymer-Dispersed LC Films

Akifumi Ogiwara; Yasunori Kuratomi; T. Karasawa; Akio Takimoto; Shinichi Mizuguchi

We have developed a new type of PS polarization converting device to realize compact LC projectors using holographic polymer dispersed liquid crystal (H-PDLC) thin films. Our films show diffraction efficiency of 80% or more for incoming P-polarized light, transmittance of 95% or more for incoming S-pdarized light.
