Abstract

Provided is an optical element substrate with which it is possible to increase the efficiency of use of light energy. An uneven structure on one substrate surface for an optical element is provided with a plurality of projections. The contour shape of the projections has an arc shape in plan view facing the one surface. The contour shape is formed by a first arc section and second arc section having different center points. The first arc section and second arc section bulge in mutually opposite directions.
