A liquid crystal display panel includes a liquid crystal layer having a twist angle of .+-.10 degree. An upper polarizer is disposed over an upper substrate of the liquid crystal display panel, and includes an absorption axis forming at an angle of 47.+-.10 degree in a clockwise direction with respect to a major axis. An upper .lamda./2 retardation film is disposed between the upper substrate and the upper polarizer, and includes .DELTA.nd1 of 260.+-.10 nm and a slow axis forming at an angle of 166.+-.10 degree in the clockwise direction with respect to the absorption axis. An upper .lamda./4 retardation film is disposed between the upper substrate and the upper .lamda./2 retardation film, and includes .DELTA.nd2 of 140.+-.10 nm and a slow axis forming at an angle of 111.+-.10 degree in the clockwise direction with respect to the absorption axis. Therefore, the optical condition of the optical film assembly is optimized to improve an image display quality.
