OPTICAL ELEMENT AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide an optical element capable of obtaining uniform light rays. SOLUTION: A method of manufacturing the optical element includes: a process of preparing an optical substrate 2; a process of applying curable resin onto the optical substrate 2 so as to form a curable resin layer 3' on the optical substrate 2; a process of embossing the curable resin layer 3' so as to form a plurality of adjoining pointed micro-protrusions 31', each of which has a tip end 311'; a process of heating the pointed micro-protrusions 31' of the curable resin layer 3' such that the tip end 311' of each of the pointed micro-protrusions 31' is softened and is spread over the remainder of the respective one of the pointed micro-protrusions 31' in order to form the adjoining pointed micro-protrusions 31' into adjoining rounded micro-protrusions 31 which cooperatively form a continuous curved surface 30; and curing the curable resin layer 3'.
