Abstract
Official abstract text for this publication.
The present invention provides an optical laminated body having a patterning polarizer layer in which a more complicated pattern can be set. The optical laminated body 1 A of the present invention has a patterning polarizer layer 3 A having at least two polarizing regions 31 A and 32 A having different single transmittances, and a substrate 2 A. The two polarizing regions 31 A and 32 A are different in thickness.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical laminated body comprising: a patterning polarizer layer having at least two polarizing regions having different single transmittances; and a substrate, wherein at the boundary of two polatizing regions, the thickness of one polarizing region and the thickness of the other polarizing region are different from each other and discontinuous. 2. The optical laminated body according to claim 1 , wherein the patterning polarizer layer is formed by applying to the surface of the substrate a coating solution containing a dichroic liquid crystal compound using a printing method. 3. The optical laminated body according to claim 1 , wherein the patterning polarizer layer contains an aligned dichroic liquid crystal compound. 4. The optical laminated body according to claim 2 , wherein the dichroic liquid crystal compound has lyotropic liquid crystallinity.
