Abstract
The problem is to provide a front plate of a TN liquid crystal panel capable of inhibiting occurrence of color unevenness caused by retardation of a polycarbonate resin sheet, even when a liquid crystal panel is observed through polarizing glasses or liquid crystal shutter glasses for 3D, while having excellent impact resistance, heat resistance and transparency.The solution means is the front plate 1 of a TN liquid crystal panel provided with the polycarbonate resin sheet 10, wherein the direction of the slow axis X or the fast axis Y of the polycarbonate resin sheet 10 is inclined by 45° with respect to the lengthwise direction L of a liquid crystal panel.
