METHOD OF LIQUID CRYSTAL CELL PRODUCTION Russian patent published in 2013 - IPC C09K19/40 C08G77/38 G02F1/33 

FIELD: chemistry.

SUBSTANCE: invention relates to field of production of liquid crystal cells for liquid crystal cell devices, which can be widely used in different information systems. Method of producing liquid crystal cell with specified angle of liquid crystal orientation consists in application on substrata of electrode current-conducting boards of orientation substance in form of solution, which includes polyorganosiloxne, solvent and catalysis gamma-aminopropyltriethoxysilane with further removal of solvent and hardening in presence of catalyst, polyorganosiloxane, and after that, assembly of cells with placement between electrode current-conducting boards of liquid crystal. As polyorganosiloxane used is oligodialkyl alkyl hydride siloxane of general formula (A): (l) [R'₂Sio]_n[R"HSio]_m[R"'₃siO_0.5]_2' (a), where R', R", R'" = CH₃, C₂H₅, п = 4 - 8, m = 6 - 9, R', R" are different from each other. Microrelief, formed on substratum, has geometrical dimensions corresponding to geometrical dimensions of liquid crystal molecules and providing angle of surface orientation in the range from 0 to 90° depending on "m" and "n" values of polyorganosiloxane of formula (A).

EFFECT: invention ensures obtaining liquid crystal cells for liquid crystal devices with orientation of liquid crystal at definite specified angle.
