<p>An optical film includes a plurality of transparent layers configured to transmit light and a plurality of reflection layers configured to reflect light. The plurality of transparent layers are disposed at spaced intervals to each other in a first direction orthogonal to a thickness direction of the optical film; each of the plurality of reflection layers is interposed between the transparent layers that are next to each other of the plurality of transparent layers; and the plurality of transparent layers include a first transparent layer and a second transparent layer that has a smaller index of refraction than that of the first transparent layer.</p> |
