Abstract
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.

A microlens array substrate comprising:
- a substrate having two surfaces on opposite sides thereof, one of the surfaces being formed with a plurality of lenses, the other of the surfaces being formed with a plurality of recesses such that each of the recesses is offset from the center of each of the lenses;
- and
- a shading layer formed in the recesses.
A microlens array substrate comprising:
- a substrate having two surfaces on opposite sides thereof, one of the surfaces being formed with a plurality of lenses, the other of the surfaces being formed with a plurality of recesses such that each of the recesses avoids being positioned right above the center of each of the lenses;
- and
- a shading layer formed in the recesses, the shading layer including a solvent in which a black dye or black pigment is dissolved together with a binder resin.
