Abstract
A method of manufacturing an optical device for a back light unit includes forming a metal ingot by adhering insulating layers between metal plates. The metal ingot is cut in a vertical direction to create original substrates each with insulating layer portions in parallel with intervals therebetween. Solder resist is deposited on at least one of a top surface and bottom surface of an original substrate.
