The present invention relates generally to the field of organic chemistry and particularly to the optical retardation films for liquid crystal displays. The present invention provides an optical film comprising a substrate having front and rear surfaces, and at least one solid retardation layer on the front surface of the substrate. Said solid retardation layer comprises rigid rod-like macromolecules comprising n organic units of the first type having general structural formula I and and k organic units of the second type having general structural formula II


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.


An organic compound has the general structural formula I. In the formula I, Core is a conjugated organic unit capable of forming a rod-like macromolecule, n is a number of the conjugated organic units in the rod-like macromolecule, G_(k )is a set of ionogenic side-groups, and k is a number of the side-groups in the set G_(k). The set of the ionogenic side-groups provide solubility of the organic compound or its salts and give rigidity to the rod-like macromolecule. The number n provides molecule anisotropy that promotes self-assembling of macromolecules in a solution of the organic compound or its salts, forming lyotropic liquid crystal. The solution is capable of forming a solid optical retardation layer of positive A-type substantially transparent to electromagnetic radiation in the visible spectral range. An optical film based on an organic compound of the general formula I and a method of making same are also disclosed.
