Abstract
A phase difference layer laminated body used in a three-dimensional liquid crystal display device, wherein unit cells are divided into groups for left and right eyes, which are given different degrees of polarization, thereby creating a three-dimensional image, further wherein the phase difference layer laminated body has a base material having orientability, and a phase difference layer made of a liquid crystal material that can form a nematic phase and formed in a pattern with two different portions, and the liquid crystal material in each of two different portions is oriented to have different refractive index anisotropy each other that conforms to the two different degrees of polarization and fixed as it is.
