ABSTRACT:
A polarizing plate includes a polarizing layer for controlling a light and producing a polarized light, the polarizing layer having a particle dispersing medium with a property of light transmission and bar-like polarizing particles which are dispersed in the particle dispersing medium and arranged in a constant direction with a magnetic field, where each of the bar-like polarizing particles is provided with a bar-like ferromagnetic particle of chromium dioxide, whose surface is coated with a conductive film.
