RETARDATION PLATE FOR STEREOSCOPIC IMAGE DISPLAY, POLARIZING ELEMENT, AND METHOD FOR PRODUCING THEM, AND STEREOSCOPIC IMAGE DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an easy-to-produce retardation plate for forming a stereoscopic image, a stereoscopic image display device and a stereoscopic image display system using the retardation plate.

SOLUTION: The retardation plate 10 for forming a stereoscopic image has a plurality of first retardation regions 11 and a plurality of second retardation regions 12 in the same plane. The first retardation regions have an in-plane phase retardation of (1/4+m)×λ at a wavelength λ, and the second retardation regions have an in-plane retardation of (3/4+n)×λ, wherein m and n are each 0 or a natural number, preferably m=n=0. The first and second retardation regions have slow axis directions 111 and 121 parallel to each other.
