Abstract

When an alignment film 416 and an overcoating film 429 are formed by flexography on the front side of a second transparent substrate 420, on which color filters 407R, 407G, and 407B are formed at a predetermined same-color pitch P1, during the procedure for manufacturing a liquid crystal device 400, the pitch of meshes of an anilox roller used in flexography and the pitch of pitches formed on the surfaces of projections of a letterpress are set to be equal to the same-color pitch P1 of the color filters 407R, 407G, and 407B, thereby preventing moiré.
