ABSTRACT:
There are provided a thin wire grid polarizer having a high transmittance, a high quenching ratio and a high degree of polarization, and a method for producing the same at low costs. A fluoridated polyimide thin film12, a hydrophilic thin film13and a hydrophobic thin film14are sequentially stacked on a glass substrate11to be pressed by a die1from the side of the hydrophobic thin film14to transfer the fine pattern of groove forming protrusions3of the die1to the hydrophobic thin film14and hydrophilic thin film13by the nano-imprinted lithography technique, and then, metal fine wires are caused to grow by plating.
