ABSTRACT:
A transmissivity controlled film12(CrO or the like), a transmissivity reduced film13(Cr or the like), and a resist film14, for instance, are sequentially formed on, e.g., a transparent substrate11. A resist is removed from an area (an area C) where a light-transmission section is to be formed, and the transmissivity reduced film13and the transmissivity controlled film12are removed from the area, thereby forming a light-transmission section. Next, a resist is removed from an area (an area A) in which a graytone section is to be formed, thereby removing the transmissivity reduced film13from that area, to thereby form a graytone section. Thus, a graytone mask is manufactured.
