Abstract
A micro lens array substrate includes a substrate including a plurality of concave portions arranged in a first direction and a second direction intersecting the first direction on one surface of the substrate, and a lens layer having a different refractive index from the substrate. The lens layer is formed on the one surface of the substrate to fill in the plurality of concave portions. The plurality of concave portions is continuous in at least one of the first direction and the second direction and is arranged to have a discontinuous part in the lens layer between two adjacent concave portions in a third direction intersecting the first and second directions. A first depth of a center of one concave portion from the discontinuous part is greater than a second depth of the discontinuous part from a surface of the lens layer.
