A method of manufacturing a microlens array substrate is provided comprising
the
steps of: closely providing a substrate precursor (30) between a first master
mold (10) having a plurality of curved surfaces (12) and a second
master mold (20) having a plurality of projections (22) to form a
substrate (32) having a plurality of lenses (34) formed by the curved
surfaces (12) and recesses (36) formed by the projections (22);
removing the first and second master molds (10, 20) from the substrate (32);
and filling the recesses (36) with a shading material (42) after
the second master mold (20) is removed.
