Abstract
The present invention relates generally to the field of organic chemistry and particularly to the nematic lyotropic liquid crystal solution and negative dispersion retardation plate for application in 3D liquid crystal displays. The negative dispersion retardation plate comprises a substrate, and at least one optically anisotropic retardation layer comprising a multi-component guest-host composition coated onto the substrate.

A nematic lyotropic liquid crystal solution comprising
- a water or water-based solvent, and
- a multi-component composition comprising
- a rigid rod-like polymer macromolecule having absorption in ultraviolet and/or near infra-red wavelength range,
- a supramolecule of a first type having absorption in ultraviolet wavelength range andformed via π-π-interaction by partially conjugated substantially planar polycyclicorganic molecules of a first type having absorption in ultraviolet wavelength range,
- a supramolecule of a second type having absorption in near-infrared wavelength range and formed via π-π-interaction by partially conjugated substantially planar polycyclicorganic molecules of a second type having absorption in near-infrared wavelength range and
- a supramolecule of a third type having absorption in ultraviolet and near-infrared wavelength ranges and formed via π-π-interaction by mix of partially conjugated substantially planar polycyclic organic molecules of the first and second types.
