ANTIREFLECTION FILM, OPTICAL MEMBER, AND METHOD FOR MANUFACTURING OPTICAL MEMBER

An optical member includes a base material and a film on the base material, the film includes hollow particles that have prickle-like protrusions on their surface, the heights of the protrusions are 3 nm or more and 20 nm or less, the proportion of the prickle-like protrusions is 3% or more and 30%...

Zusammenfassung:	An optical member includes a base material and a film on the base material, the film includes hollow particles that have prickle-like protrusions on their surface, the heights of the protrusions are 3 nm or more and 20 nm or less, the proportion of the prickle-like protrusions is 3% or more and 30% or less of the particle surface, and the film includes 50 percent by volume or more and 68 percent by volume or less of hollow particles. Consequently, an antireflection film having a low refractive index and a low level of scattering in combination is provided.
