    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.

    摘要： There is provided a method of producing a polyvinyl alcohol (PVA) film polarizer having an excellent durability, the method comprising dyeing, cross-linking, stretching, and drying, wherein additives containing phosphorus is inputted into one or more of the dyeing, the cross-linking, and the stretching. In this case, the additives containing phosphorus may be selected from a group consisting of a phosphoric acid, potassium phosphate monobasic, potassium phosphate dibasic, magnesium phosphate dibasic, sodium phosphate monobasic, and ammonium phosphate monobasic. An amount of the additives containing phosphorus in an added solution may be 0.01 to 15 wt %. As described above, when inputting the additives containing phosphorus while producing a polarizer, cross-linking between iodine and a polymer matrix becomes strong due to the phosphorus contained in the additives, thereby producing a polarizer having an excellent durability, and particularly, an excellent thermal stability.
