Abstract: The invention pertains to a single-polarizer, normally white reflective display comprising an STN-LCD cell, a reflector, one polarizer, and a twisted retardation layer, wherein the sign of the twist angle of the STN-LCD cell (TSTN) is opposite to the twist angle of the twisted retardation layer (TRL) and |TSTN−TRL| is between 90° and 160°, and |RSTN−RRL| is 10-700 nm, wherein RSTN and RRL stand for the retardation values of the STN-LCD cell and the retardation layer, respectively, and the difference between the dispersion of the retardation layer and the STN-LCD cell is more than 5%, wherein the dispersion is defined as the ratio of the retardation value at &lgr;=436 nm to the retardation value at &lgr;=668 nm.

Abstract: The invention is in the field of retardation layers comprising high-molecular weight liquid-crystalline material for liquid-crystalline displays. The invention is directed to a retardation layer for a liquid-crystalline display comprising high-molecular weight liquid-crystalline material, wherein the dispersion has been adapted to that of the active liquid-crystalline cell by varying the mesogenic groups of the high-molecular weight liquid-crystalline material, so that the difference in dispersion between the active cell and the retardation layer in the wavelength area of 400-800 nm is not more than 0.1.
