Abstract
A micro lens array substrate includes a substrate having optical transparency and a lens layer having optical transparency and a different refractive index from that of the substrate, which is formed in such a manner as to fill in a concave portion arranged in one surface of the substrate in the X-direction, the Y-direction, and the W-direction. A through-hole is provided in the lens layer, between the adjacent concave portions in the W-direction in the lens layer, and the lens layer is continuous between the adjacent concave portions in the X-direction or in the Y-direction.
