An optical film has a plurality of aligned convex microlenses, each of which has a region α and a region β, region β forming the outer part of the convex shape of the microlens and positioned so as to cover region α. Both region α and region β contain a resin, and the refractive index of the resin in region α is higher than the refractive index of the resin in region β; region β contains fine particles, and region α contains fine particles, and the content of the fine particles contained in region α is lower than the content of the fine particles contained in region β; or region α contains fine particles, and region β contains fine particles, and the content of the fine particles contained in region α is higher than the content of the fine particles contained in region β.
