Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce difficulty in cutting a pattern retardation film having a fine pattern and aligning the pattern retardation film with other optical elements.SOLUTION: A pattern retardation film has a display pixel region that is laminated to a display pixel part of an image display device. The display pixel region has a pattern in which first retardation regions and second retardation regions are alternately arranged in stripes and at intervals of pitch d; and the first retardation regions differ from the second retardation regions in at least one aspect of in-plane slow axis direction and retardation. The pattern retardation film also has non-display pixel regions in which linear marks are at least made at a distance of doutside the display pixel region in the direction parallel to the longitudinal direction of the first and second retardation regions, where dis not equal to d.
