CORRECTION METHOD OF EXCIPIENT MOLD, EXCIPIENT MOLD, ANTIREFLECTION ARTICLE, PICTURE DISPLAY UNIT, AND SHOW CASE

PROBLEM TO BE SOLVED: To remove a foreign matter adhering to an excipient mold that becomes a factor of degradation of an antireflection function of a fine projection relating to a moth-eye structure of an antireflection article and a poor appearance.SOLUTION: A correction method of a roll plate 13 is a correction method of the roll plate 13 that performs excipient of fine projections of an antireflection article 1 in which the fine projections are tightly arranged, and a distance of the neighboring fine projections is at most a shortest wavelength of a wavelength band of an electromagnetic wave in which antireflection is achieved, the roll plate 13 includes an excipient layer 13c in which a fine rugged shape is formed that performs excipient of fine projections to a surface of the antireflection article 1, the correction method of the roll plate 13 includes: a foreign matter detection step in which a foreign matter F adhering to a surface of the excipient layer 13c is detected; and a foreign matter removal step in which the foreign matter F detected at the foreign matter detection step is removed by the irradiation of a laser beam.
