<P>PROBLEM TO BE SOLVED: To provide a laminated phase difference film for suppressing cross talk and color shift. <P>SOLUTION: A laminated phase difference film includes a 1/2 wavelength plate and a 1/4 wavelength plate. If the laminated phase difference film is provided in a display device, the angle θa which a reference direction, being an in-plane direction, perpendicular to the transmission axis of a first wavelength plate of the display device forms with the slow axis of the 1/2 wavelength plate, and the angle θb which the reference direction forms with the slow axis of the 1/4 wavelength plate satisfy the relationships of formula (1) and formula (2): formula (1) is 2θa-140°≤θb≤2θa-130° and formula (2) is 100°≤θa≤105°. <P>COPYRIGHT: (C)2013,JPO&INPIT |
