A new antireflective and antistatic coating with ultra-fine particles is developed. The coating consists of two layers; an antireflective layer of SiO2 ultra-fine particles that is uniformly a single particle thick, and a conductive layer composed of multiple SnO2 ultra-fine particles.
The outer surface of the antireflective layer is alternately concave convex, owing to the arrangement of SiO2 particles. The refractive index of this layer therefore decreases gradually from its inner to its outer surface. Thus, the total reflectivity can be reduced.
The coating provides low reflectivity and electrical resistance in addition to high resolution and contrast.
