Abstract
A light valve device having a first optical retardance is optically coupled to a modified skew angle compensator, which has a second optical retardance, and the sum of the first optical retardance and the second optical retardance equals a retardance of a quarter-wave retarder over a prescribed wavelength range. A method of substantially preventing dark-state light from being transmitted to display optics in a liquid crystal (LC) display includes rotating the dark state light so that a polarization beam splitter (PBS) transmits the light back to the source.
