A microlens array includes a first lens, a second lens, and a third lens. The first lens and the second lens are adjacent to each other and are arranged neighboring in a first direction. The first lens and the third lens are adjacent to each other and are arranged neighboring in a second direction substantially orthogonal to the first direction. A gap between an apex of the first lens and an apex of the second lens is different to a gap between the apex of the first lens and an apex of the third lens.
