Abstract
A polarizing plate includes a polarizer and at least one protective film on at least one side of the polarizer. The protective film has an in-plane retardation (Re) of greater than about 10,000 nm at a wavelength of 550 nm, as calculated by Re=(nx−ny)×d, wherein nx and ny are indexes of refraction in x-axis and y-axis directions of the protective film, respectively, and d is a thickness of the protective film.
