Abstract

A viewing device is disclosed. The device includes a projector that projects a first imaged light, and a polarizing beam splitter plate that receives the projected first imaged light from the projector and reflects the received first imaged light for viewing by a viewer. The polarizing beam splitter plate also receives a second image and transmits the second image for viewing by the viewer. The polarizing beam splitter plate includes a substrate and a multilayer optical film reflective polarizer that is adhered to the substrate. The reflective polarizer substantially reflects polarized light having a first polarization state and substantially transmits polarized light having a second polarization state perpendicular to the first polarization state. The polarizing beam splitter plate includes a first outermost major surface and an opposing second outermost major surface that makes an angle of less than about 20 degrees with the first outermost major surface. The polarizing beam splitter plate reflects the received first imaged light towards the viewer with the reflected first imaged light having an effective pixel resolution of less than 12 microns.
