Patent ID: 8658347

Claim:
A method of manufacturing a micro lens array comprising a plurality of micro lenses and a mask pattern where a focus is formed by the plurality of micro lenses, the method comprising: disposing a transparent film on which photoresist is coated at one side of the plurality of micro lenses; hardening the photoresist on a focus of the plurality of micro lenses by irradiating ultraviolet rays on the plurality of micro lenses; removing the photoresist except for a region where it is hardened; depositing a metal on the transparent film; and removing the photoresist on the transparent film, wherein the plurality of micro lenses is manufactured by: preparing a master plate having a plurality of molding grooves on one side, inside a vacuum chamber; forming a shading film for blocking a beam, by depositing a metal or coating ink or black matrix between the plurality of molding grooves; preparing a substrate constituting a raw material of a micro lens, inside the vacuum chamber; forming a vacuum inside the vacuum chamber; adhering the master plate and the substrate; heating the substrate; releasing the vacuum inside the vacuum chamber; and forming the plurality of micro lenses by separating the master plate and the substrate.
