Abstract

See full text

An antireflection coating includes one or more inorganic antireflection layers (typically metal oxide or silica layers) and a polymer layer cured in situ, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 to 700 nm and a thickness of from about 20 to about 200 nm. The polymer layer provides good scratch and fingerprint protection, and also enables the thicknesses of the inorganic antireflection layers to be reduced, thereby reducing the cost of the coating.
