Abstract: A microlens array includes microlenses disposed in order and a low refractive index layer that contains a hollow filler and a medium and is formed on the microlenses and that has a lower refractive index than the refractive index of the microlenses. The proportion of white pixels in a binarized plan view image of the low refractive index layer is 76% or less.
