摘要
A manufacturing method of a filter, including the following steps: defining an adhesive layer on a surface of a substrate according to a filter pattern; covering the surface of the substrate by a conductive layer, wherein the conductive layer comprises a first covering part and a second covering part, wherein the first covering part and the second covering part are non-overlapping. In an aspect, the first covering part of the conductive layer is attached to the adhesive layer according to the filter pattern and the second covering part is not attached to the adhesive layer. In an aspect, the second covering part of the conductive layer is attached to the surface of the substrate to form the filter pattern.
