ABSTRACT:
A multi-layered liquid crystal display device has a stack of liquid crystal layers. Each of the liquid crystal layers is disposed in such an orientation vector between each pair of plates as to bring its good display contrast area following the conversion of the molecular alignment into agreement with each other with regard to a whole display area.
