Patent ID: 10222695

Abstract:
Provided is a method for manufacturing a transparent substrate according to an exemplary embodiment of the present invention including: a) forming a photoresist layer satisfying D=m*(λ/2n); b) manufacturing a ring-shaped pattern by exposing the photoresist layer and developing the exposed photoresist layer, using a photo mask including a transparent base and a plate-type metal dot formed contacting a light emitting surface of the transparent base; c) manufacturing a second mold to which the ring-shaped pattern is reversely transferred by using a substrate on which the ring-shaped pattern is formed as a first mold; and d) manufacturing the transparent substrate in which a ring-shaped transparent protrusion is integrally formed with the transparent base by filling a liquefied transparent resin in the second mold and curing the transparent resin and removing the second mold to transfer the ring-shaped pattern.
