Abstract:
1. A liquid crystal display comprising: a lower panel; an upper panel facing the lower panel and including a plurality of red color filters, green color filters, and blue color filters, the color filters having corresponding wavelengths λr, λg, and λb corresponding to red, green and blue, respectively; a liquid crystal layer interposed between the lower and upper panels; a first compensation film on an outer surface of the lower panel or the upper panel, wherein the first compensation film has phase retardation values Rth_r, Rth_g, and Rth_b in a thickness direction of the first compensation film and corresponding to the wavelengths of red, green, and blue, respectively; a lower polarizer disposed on the outer surface of the lower panel; and an upper polarizer on the outer surface of the upper panel, wherein the liquid crystal layer, the lower and upper polarizers and the lower and upper panels have phase retardation values RthL_r, RthL_g, and RthL_b in a thickness direction and corresponding to red, green, and blue wavelengths respectively; wherein the wavelengths and phase retardation values satisfy the equation
