POLYMERIZED LIQUID CRYSTAL FILM WITH RETARDATION OR ORIENTATION PATTERN

PROBLEM TO BE SOLVED: To provide a retardation film for use in active matrix color LCDs which allows more efficient conversion between linear polarized state and circular polarized state for light of different wavelengths. SOLUTION: A patterned film having a polymerized liquid crystal (LC) material...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a retardation film for use in active matrix color LCDs which allows more efficient conversion between linear polarized state and circular polarized state for light of different wavelengths. SOLUTION: A patterned film having a polymerized liquid crystal (LC) material includes at least two regions with different retardation and at least two regions with different orientation of the LC material, wherein the regions differing in retardation can also differ in retardation, or they can be different regions.
