摘要：
A microlens array includes N lenses ranging from a 1st lens to an Nth lens and a lens arrangement area. N is a positive integer. The lens arrangement area has the N lenses arranged in array. The lens arrangement area receives light emitted from a light source. An ith (i being 1st to Nth) lens satisfies a conditional expression below: −20°≤θ≤20° where θ denotes an angle formed by a main-axis orientation of double refraction and a reference orientation.
