  • Patent number: 9651727
    Abstract: A polarizer includes a base substrate and a metal pattern disposed on the base substrate and forming a wire grid. The wire grid has a width and a height and spaced apart from adjacent wire grid by a separation distance. A pitch is a sum of the width and the separation distance.
