A PRISM-PATTERNED BROADBAND REFLECTION TYPED BRIGHTNESS ENHANCEMENT POLARIZER, THE MANUFACTURING METHOD THEREOF AND A LIQUID CRYSTAL DISPLAY HAVING THE SAME

摘要

An integral type broadband-reflective high brightness polarizer having a prism pattern, a manufacturing method thereof, and an LCD having the same are provided to prevent a light loss at an interface by forming a prism pattern coating layer formed at one side of a polarizer as one body with the polarizer. A broadband reflective polarizer includes a lamination cholesteric liquid crystal film and a 1/4lambda phase difference film. The lamination cholesteric liquid crystal film has a broadband selective reflective wavelength region and is formed by laminating a plurality of cholesteric liquid crystal films with different selective reflective wavelength regions by varying a mixture ratio between a curable nematic liquid crystal compound expressed by a chemical formula 1 and a curable chiral compound expressed by a chemical formula 2. The 1/4lambda phase difference film is laminated on one face of the lamination cholesteric liquid crystal film. A integral type broadband-reflective high brightness polarizer consists of the broadband reflective polarizer and a prism pattern coating layer formed at one face of the broadband reflective polarizer.
