A method of manufacturing a microlens substrate 1 is disclosed. The microlens substrate 1 is composed of a base substrate 4 having two major surfaces and having light transparency and a lens portion 2 having a plurality of microlenses 21 . The lens portion 2 is provided on one of the two major surfaces 24 of the base substrate 4 . The method includes the steps of: preparing a substrate with concave portions having two major surfaces, a plurality of concave portions being formed on one of the two major surfaces of the substrate with concave portions; supplying a resin material for forming the lens portion 2 onto the one major surface of the substrate with concave portions on which the plurality of concave portions are formed, the resin material being constituted from a photopolymer having a photocuring property as a main component and containing an additive constituted from at least one of a diffusing agent and a coloring agent, the diffusing agent having a function of diffusing incident light to the resin material; preparing the base substrate 4 ; mounting the base substrate 4 on the supplied resin material; photocuring the resin material by light to form the lens portion 2 in a state where the base substrate 4 is in contact with the resin material, whereby the base substrate 4 is bonded to the photocured resin material; and removing the substrate with concave portions from the photocured resin material to obtain the microlens substrate 1 provided with the lens portion 2.
