Abstract
A method for producing a polarizing element includes: forming particulate materials of a metal halide on a glass substrate; forming a protective film that covers the particulate materials in a non-plasma environment; stretching the particulate materials by heating and stretching the glass substrate; and forming acicular metal particles by reducing the metal halide constituting the stretched particulate materials.
Claims4
A method tor producing a polarizing element, comprising:
- forming particulate materials containing a metal halide on a glass substrate;
- forming a protective film that covers the particulate materials in a non-plasma environment;
- stretching the particulate materials by stretching the glass substrate at a temperature at which the glass substrate is softened;
- and
- forming acicular metal particles by reducing the metal halide constituting the stretched particulate materials.
