Liquid crystal on silicon (LCoS or LCOS) is a miniaturized reflective active-matrix liquid-crystal display or "microdisplay" using a liquid crystal layer on top of a silicon backplane. It is also known as a spatial light modulator. LCoS initially was developed for projection televisions, but has since found additional uses in wavelength selective switching, structured illumination, near-eye displays and optical pulse shaping.

LCoS is distinct from other LCD projector technologies which use transmissive LCD, allowing light to pass through the light processing unit (s). LCoS is more similar to DLP micro-mirror displays.
