Abstract
A polarized element formed by arranging a dichroic molecule in a micropattern form on a thin film layer of a liquid crystalline resin having a photoactive group irradiated by a linearly polarized light. The micropattern polarized element can be produced without need of a very high position-matching precision as sticking.
