Abstract
A black-white liquid crystal display using a cholesteric liquid crystal material and a method for manufacturing such a liquid crystal display using polymerization/phase-separation, resulting in diffused polymeric molecules and polymeric cell walls, so as to minimize the manufacturing time, strengthen the polymeric wall and enhance the contrast ratio as well as the brightness.
