METHOD FOR PRODUCING MICROLENS ARRAY, METALLIC MOLD FOR DUPLICATING MICROLENS ARRAY AND METHOD FOR PRODUCING DUPLICATE MICROLENS ARRAY

摘要

PURPOSE: A micro lens array manufacturing method, a metal mold manufacturing method for duplicating a micro lens array, and a duplicated micro lens array manufacturing method are provided to realize a large production area by using a roll to roll process. CONSTITUTION: A metal thin film is coated on the top of a micro lens array to form a seed layer(S21). An electric plating is implemented for manufacturing a metal mold(S22). The micro lens array is removed from the metal mold(S23).
