Abstract
A composition of an optical film contains silica-based hollow microparticles, a matrix precursor, a nonvolatile liquid, and a volatile solvent. The nonvolatile liquid has a vapor pressure of 500 Pa or less, a boiling point of 250° C. or higher, and a refractive index in a range from 1.4 to 1.5, inclusive. The volatile solvent is more volatile than the nonvolatile liquid. The content of the nonvolatile liquid is in the range from 5 to 30 parts by mass, inclusive, per 100 parts by mass of the sum of the silica-based hollow microparticles and the matrix precursor.
