Abstract: A display panel assembly and a display device having the same are provided to improve the side luminance asymmetry of an OCB(Optically Compensated Bend)-mode liquid crystal panel effectively by applying an upper polarizing film having a high haze characteristic in order to improve the dispersion of light and to secure a surface low-reflective characteristic. A display panel assembly comprises a display panel(100), an upper polarizing plate(140), and a lower polarizing plate(130). The display panel has the first substrate(110), the second substrate(120), and an OCB-mode liquid crystal layer. The first substrate and the second substrate face each other. The OCB-mode liquid crystal layer is inserted between the first substrate and the second substrate. The upper polarizing plate, arranged at the top of the display panel, has a value of more than haze 64. The haze value of the upper polarizing plate is between 64 to 90. The lower polarizing plate is arranged at the bottom of the display panel.

Abstract: A method for driving an LCD(Liquid Crystal Display) device is provided to enhance display quality by executing micro gamma compensation based on gray scale areas. Plural primary gray scale values corresponding to plural pixels are inputted from the outside(S110). By dividing the pixels into plural pixel groups, a first average primary gray scale value that is an average value of primary gray scale values, is calculated(S120). A second average primary gray scale value that is an average value of the first average primary gray scale value, is calculated(S130). A difference value between average primary gray scale values of first and second pixel groups is calculated and a reference gamma curve is compensated by using plural compensation gamma curves based on the difference value(S140). By applying one of the compensation gamma curves and the reference gamma curve based on a gray scale interval including the second average primary gray scale value, images are displayed(S150).
