Stamper for use in forming planar micro-lens array and method for forming thereof |
摘要 |
For providing a stamper for forming a planar micro-lens array, a stamper is prepared by forming plural concave portions 2 for forming lens portion upon a stamping surface thereof, and a trap portion 3 is provided surrounding said plural concave portions and continuing until an outer edge thereof. Then, onto the stamping surface, on which a release agent 4 is applied, there is applied a high refractive index resin 5, and a glass substrate 6 is pressed onto the high refractive index resin 5 to exude it. With this operation, the high refractive index resin 5 is filled into each of the plural concave portions 2, and any excess is received or accommodated in the trap portion 3, thereby preventing excess resin from being forced outside.
