We describe the design, fabrication and contrast measurement results of a high performance, all‐inorganic, grating‐based contrast enhancer for an LCoS‐based projection display that has these attributes: complete A/C‐plate compensation, accurate retardance targeting, excellent retardance magnitude and axis uniformity and environmental durability. An overall system contrast of more than 5500:1 with f/2.4 cone illumination has been obtained.
