A microlens array described below is disclosed. In the microlens array, a plurality of microlenses are formed with an irregularity or probability-distributed regularity so as to differ from a hypothetical base pattern, the hypothetical base pattern having apexes of hypothetical microlenses each spaced apart from every adjacent microlens thereof by an equal distance L. All the apex positions of the microlenses lie within circles each centered on an apex position in said hypothetical base pattern and having a radius equal to or smaller than 0.3L, or meet a condition: 0.4L<=P<=1.6L. In this way, a microlens array with bright and clean viewing characteristics and a high reproducibility of a shape of each microlens is provided.
