Abstract:
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 1A of the present invention has a patterning polarizer layer 3A having at least two polarizing regions 31A and 32A having different single transmittances, and a substrate 2A. The two polarizing regions 31A and 32A are different in thickness.
