An optical film that is provided with a plurality of aligned convex microlenses (10), each of which has a region ± (11) and a region ² (12), said region forming the outer part of the convex shape of the microlens and positioned so as to cover the region ±. This optical film is characterized in that: both the region ± and the region contain a resin, and the refractive index (n 1 ) of the resin in the region ± is higher than the refractive index (n 2 ) of the resin in the region ²; the region contains fine particles, and if necessary, the region ± contains fine particles, and the content (P 1 ) of the fine particles contained in the region ± is lower than the content (P 2 ) of the fine particles contained in the region ²; or the region ± contains fine particles, and if necessary, the region contains fine particles, and the content (P 1 ) of the fine particles contained in the region ± is higher than the content (P 2 ) of the fine particles contained in the region ². |
