METHOD FOR MANUFACTURING ALIGNMENT IDENTIFIER OF SPACER, METHOD FOR DETECTING POSITION ACCURACY, AND COLOR FILTER AND MANUFACTURING METHOD THEREOF

摘要

A method for manufacturing an alignment identifier of a spacer and method for detecting accuracy comprise: when manufacturing a black matrix (BM) layer of a color filter, forming, on a substrate, at least one first sub-pixel opening region (200, 400) and a plurality of second sub-pixel opening regions, wherein a dimension of the first sub-pixel opening region (200, 400) is less than a dimension of the second sub-pixel opening regions; and when manufacturing a spacer layer, manufacturing, at a specified position surrounding the first sub-pixel opening region (200, 400), an alignment identifier (410) of the spacer layer.
