POLARIZING SHEET CONSISTING OF DISCOTIC LIQUID CRYSTAL FILM INCLUDING BAR SHAPED DICHROIC COLORING MATTER

摘要

PROBLEM TO BE SOLVED: To inexpensively provide a coloring matter type polarizing film having both high durability and high polarization by adopting a simple manufacturing method. ;SOLUTION: A polarizing sheet including a discotic liquid crystal film consisting of a bar-shaped dichroic coloring matter arranged in a state such that the axis of inertia is included in a plane vertical to the surface of the sheet by discotic liquid crystalline molecules fixed in a state such that the molecules are oriented vertically to the surface of the sheet and uniaxially.;COPYRIGHT: (C)2001,JPO
