A process for fabricating a molding stamp mainly includes the steps of: (1) attaching a framework onto a substrate, the framework defining a number of through holes therein so that the framework and the substrate cooperatively define a number of molding cavities; (2) applying a UV curable resin in one of the molding cavities; (3) molding the UV curable resin in the one of the molding cavities using a printing stamp having a predetermined microlens pattern; (4) curing the UV curable resin to form a microlens unit; (5) removing the printing stamp; (6) repeating the steps (2) through (5) to form a number of microlens units on the substrate; (7) removing the framework from the substrate; (8) applying a thermosetting resin on the substrate to cover the microlens units; (9) curing the thermosetting resin to form the molding stamp; and (10) separating the molding stamp from the substrate.
