Abstract
An array of reflective LCSLM pixels formed on a substrate with a light polarizing layer positioned in overlying relationship to the array. A mounting support includes a waveguide portion having a light input, a light output, and a mirrored surface directing light from the input toward the output, the polarizing layer and the array are mounted on the input. A light source is mounted in the mirrored surface to direct light through the polarizing layer and evenly illuminate the array. Light reflected from the array is directed through the polarizing layer and onto the mirrored surface. A diffuser at the output forms an image plane for the reflected light. Electrical connections are made from the array, through leads in the support and to external contacts.
