Abstract
According to embodiments of the present invention, a retarder for a liquid crystal on silicon microdisplay cell may include a twisted nematic cell sandwiched between index of refraction matching layers, isotropic material (for example, glass) disposed on the top and bottom index matching layers and antireflective material disposed on the top and bottom isotropic layers. In one embodiment, the retarder includes a fast axis oriented substantially ninety degrees out of phase relative to a fast axis of the residual retardance of the liquid crystal on silicon microdisplay cell.
