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.
