PURPOSE:To form directly a micro lens on an optic by a method in which the stamper transparent to ultraviolet is used, and the photosensitive resin layer formed on the optic is formed into the shape of the micro lens, and then said photosensitive resin layer is cured by radiating ultraviolet through said stamper. CONSTITUTION:Metal is electro-deposited on the mater pattern 1 of a micro lens 10, and a master 2 is formed. Metal is electro-deposited also on the master, thereby forming a mother 3. Next a photosensitive resin layer 4 is formed on one surface of the base plate 5 composed of the same material as that of base plates 9a, 9b of e.g. a liquid crystal indicative panel 11 on which the micro lens 10 is to be formed. While the mother 3 is pushed onto said resin layer, ultraviolet is radiated thereon,and the resin layer is cured, and then the mother 3 is removed, thereby obtaining a stamper 6. The photosensitive resin layer 8 having the refraction index similar to that of the borosilicate glass which is the material of the base plate 9a, is formed on one base plate 9a of a pair of base plates 9a, 9b of the liquid crystal panel 11, and by pushing the stamper 6 onto said resin layer, the shape of the micro lens 10 is formed. Ultraviolet is radiated on said shape through the stamper 6, and then the stamper 6 is removed, thereby forming the micro lens 10. |
