Abstract
The present invention provides a method of manufacturing a microlens array substrate 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.
Claims22
A method of manufacturing a microlens array substrate comprising the steps of:
- closely providing a substrate precursor between a first master mold having a plurality of curved surfaces and a second master mold having a plurality of projections to form a substrate having a plurality of lenses formed by the curved surfaces and recesses formed by the projections;
- removing the first and second master molds from the substrate;
- and
- filling the recesses with a shading material after the second master mold is removed.
A microlens array substrate comprising:
- a plurality of lenses formed on one surface of the microlens array substrate;
- a plurality of recesses formed on the other surface of the microlens array substrate 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.
