Abstract
A microlens array includes a cell, and P lenses (P is an integer of 4 or more) arranged in the cell, in which the apexes of the P lenses are arranged such that symmetry is at least partially broken, when viewed in plan view. In this way, it is possible to suppress diffraction caused by regularity in the lens shape in the cell. Accordingly, it is possible to realize a microlens with a high utilization efficiency of light.
