Abstract

An optical substrate according to one embodiment includes a support substrate, and a projection-depression structure layer on a surface of which shapes of projections and depressions are formed, the projection-depression structure layer being laminated on the support substrate. The extending directions of projection portions contained in the projection-depression structure layer are irregularly distributed seen in planar view. An outline seen in planar view of a projection portion contained in a region per unit area of the projection-depression structure layer includes more straight line sections than curved line sections.
