Zusammenfassung:The problem is to provide a front plate of a TN liquid crystal display device capable of reducing occurrence of color unevenness caused by retardation of a polycarbonate resin sheet, even when the 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 are that the direction of the slow axis or the fast axis of a polycarbonate resin sheet is parallel to the lengthwise direction of a TN liquid crystal panel, and that retardation is not less than 5000 nm.
