Abstract
There is provided a circular polarizing plate for a reflective liquid crystal display, the circular polarizing plate including: a polarizing plate including a polarizer having an absorption axis forming an angle of 85° to 95° with respect to an alignment direction of liquid crystals of a liquid crystal cell, disposed toward an upper substrate, and a ¼ wavelength plate having an optical axis forming an angle of 130° to 140° with respect to the alignment direction of the liquid crystals of the liquid crystal cell, disposed toward the upper substrate, wherein the ¼ wavelength plate has reverse wavelength dispersion characteristics.
