Abstract
A low-reflection film includes: a hard coating layer; and a first refraction layer, a second refraction layer, and a third refraction layer having different refractive indexes and stacked on the hard coating layer, in which the refractive index of the third refraction layer positioned furthest from the hard coating layer is a lowest, and the third refraction layer includes a compound represented by Chemical Formula 1, a compound represented by Chemical Formula 2, and a hollow material.
