Abstract
An antireflection film and method of making same includes a substrate having a first surface and a second surface, an inorganic layer deposited on the first surface of the substrate, and an optically active polymer layer formed by curing a curable composition in situ on the inorganic layer, the polymer layer having a refractive index not greater than about 1.53 over the wavelength range of 400 nm to 700 nm and a thickness of from about 20 nm to about 200 nm, and an adhesive layer deposited on the second surface of the substrate.
