摘要 |
PCT No. PCT/EP94/03246 Sec. 371 Date May 17, 1996 Sec. 102(e) Date May 17, 1996 PCT Filed Sep. 29, 1994 PCT Pub. No. WO95/09379 PCT Pub. Date Apr. 6, 1995The 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. |
