Patent ID: 8508677

Claim:
A reflective liquid crystal projector comprising: an illumination optical system for converting light emitted from a light source into illumination light polarized in a predetermined polarization direction; a reflective liquid crystal display panel for modulating said illumination light into image light; a projection optical system for projecting said image light on a screen; and a polarizing beam splitter sheet including a transparent substrate in a form of sheet having flexibility and a polarization separating layer disposed on said substrate, said polarizing beam splitter sheet reflecting said illumination light made incident thereon along an incident light axis toward said reflective liquid crystal display panel along a reflection light axis approximately perpendicular to said incident light axis, and transmitting said image light from said reflective liquid crystal display panel toward said projection optical system, and said polarizing beam splitter sheet being curved into a partially cylindrical shape so as to be concave or convex along a central axis which is perpendicular to both said incident light axis and said reflection light axis.
