    摘要： Provided are a circular polarizer and a reflective liquid crystal display including the same. The circular polarizer includes a polarizer comprising a polarizing film in which an absorption axis has an angle of about 85° to about 95° with respect to a liquid crystal alignment direction of a liquid crystal cell, where, in CIE coordinates, a color “a” is about −1 to about −0.6 and a color “b” is about 0.3 to about 2.5 and a ¼ wavelength plate in which an optical axis has an angle of about 130° to about 140° with respect to the liquid crystal alignment direction of the light crystal cell. When the circular polarizer is used, the visibility and color tone of the reflective liquid crystal display may be improved.
