ABSTRACT:
A lengthy grid polarizer film comprising a lengthy resin film and a plurality of grid lines provided on the surface and/or inside of the resin film and extending substantially in parallel with each other are provided, the grid lines being made of a material G being 1.0 or more in the absolute value of the difference between the real part n1and the imaginary part κ1of the complex refractive index (N1=n1−iκ1), said resin film having a plurality of rows of grooves formed extending substantially in parallel with each other on its surface, and said grid line being made of a thin film of the laminated material G on the bottom face of the grooves and/or on the top face of ridges located between the adjacent grooves. A lengthy optical laminated body comprises the lengthy grid polarizer film and another lengthy polarizing optical film.
