To provide a new and improved optical body capable of enhancing light extraction efficiency.SOLUTION: An optical body 1 includes a substrate and a light extraction part 11 formed on a surface of the substrate and extracting internal propagation light, which is introduced through a side face of the substrate into the substrate, to the outside of the substrate. The light extraction part 11 is constituted by a convex microlens array, in which the maximum inclination angle of the convex microlens array is approximately equal to the maximum propagation angle of the internal propagation light.SELECTED DRAWING: Figure 1
