PROBLEM TO BE SOLVED: To provide a microlens array substrate capable of preventing cracks of a lens layer and improving light utilization efficiency, a manufacturing method for the same, and an electro-optical device and electronic device having the same.SOLUTION: A microlens array substrate 10 includes; an optically transmissive substrate 11 having concave portions 11b, which are arrayed in an X direction, Y direction crossing the X direction, and W direction crossing the X and Y directions, formed on a surface 11a thereof; and a lens layer 12 which is formed on the surface 11a of the substrate 11 to fill the concave portions 11b, is optically transmissive, and has a refractive index different from that of the substrate 11. The lens layer 12 is provided with through holes 13 between every adjacent concave portions 11b in the W direction, out of the X, Y, and W directions, in a planar view and is continuous between every adjacent concave portions 11b in at least either the X direction or Y direction. |
