Patent ID: 6842289

Claim:
A method for manufacturing a microlens array comprising the steps of: providing a first light transmitting layer, forming second light transmitting layers on the first light transmitting layer, wherein the first light transmitting layer has a plurality of recessed parts and partitions for delimiting the recessed parts, at least a portion of an inner surface of each recessed part being a lens surface, the second light transmitting layers are formed in the respective recessed parts such that the second light transmitting layers avoid the partitions of the first light transmitting layer, and the second light transmitting layers are formed such that surfaces of the second light transmitting layers form lens surfaces for the respective recessed parts of the first light transmitting layer, wherein the first light transmitting layer is provided with light transmitting layer precursors thereon, and then the second light transmitting layers are formed, and wherein the surfaces of the partitions of the first light transmitting layer comprise a material having a low affinity for the light transmitting layer precursors, and each surface of the light transmitting layer precursors forms a raised surface for each recessed part by repulsion of the light transmitting layer precursors by the partitions.
