摘要：
First rubbing is performed on an entire surface of an alignment film (22) provided on a substrate (21), and then a mask part (51a) for masking a first region and a region of an alignment mark is formed on the alignment film (22) by using a resist layer (51). After performing second rubbing on the alignment film (22) through the mask part (51a), the mask part (51a) is removed, and a liquid crystal layer (23) is formed on the alignment film (22). In this way, the alignment mark is formed as a region having an optical function different from an optical function of a region surrounding the alignment mark.Thus, it is possible to produce a substrate (21) having an alignment mark formed without increasing processing steps at such a position as to contact the liquid crystal layer (23).
