Patent ID: 8416376

Claim:
An in-plane switching type liquid crystal display comprising: (a) first and second polarizing plates facing each other and spaced from each other; (b) a liquid crystal cell situated between said first and second polarizing plates, and (c) at least one compensation structure; wherein the director orientation of the liquid crystal layer of said cell being controlled by an electric field parallel to the polarizing plates, wherein one compensating structure located between the liquid crystal cell and the first polarizing plate, wherein the polarizing plates have transmission axes perpendicular to each other, and the compensation structure comprises at least one retardation layer of supramolecules comprising at least one polycyclic organic compound with a conjugated π-system and functional groups which are capable of forming non-covalent bonds between said supramolecules, wherein the organic compound has a general structural formula (I) where Sys is at least partially conjugated substantially planar heterocyclic or cyclic molecular system, X is a carboxylic group —COOH, m is 0, 1, 2, 3 or 4; Y is a sulfonic group —SO 3 H, n is 0, 1, 2, 3 or 4; Z is an amide of a carboxylic acid group, p is 0, 1, 2, 3 or 4; Q is an amide of a sulfonic acid group, v is 0, 1, 2, 3 or 4; K is a counterion; s is the number of counterions providing neutral state of the molecule; R is a substituent selected from the list comprising CH 3 , C 2 H 5 , NO 2 , cl, BR, F, CF 3 CN, OH, OCH 3 , OC 2 H 5 , OCOCH 3 , OCN, SCN, NH 2 and NHCOCH 3 , and w is 0, 1, 2, 3 or 4; and wherein the molecular system Sys is substantially transparent in the visible spectral range.
