Patent ID: 8072561

Claim:
A liquid crystal display projection system comprising: a light source; a first polarizer for receiving light from the light source, the first polarizer having a transmission axis oriented to transmit light having a first polarization; a liquid crystal display panel for receiving light transmitted through the first polarizer and for selectively modulating said transmitted light; a second polarizer for receiving light transmitted through the liquid crystal display panel, the second polarizer having a transmission axis oriented substantially perpendicular to the transmission axis of the first polarizer; and a compensating plate including: a first birefringent element having an optic axis oriented at a first angle to the plate normal, the first angle greater than zero degrees; a second birefringent element having an optic axis oriented at a second angle to the plate normal, the second angle substantially equal to zero degrees, wherein the compensating plate is tilted relative to a plane of the liquid crystal display panel.
