METHOD FOR OBTAINING HOMEOTROPICALLY ORIENTED LIQUID CRYSTAL LAYER OF LIQUID CRYSTAL DEVICE Russian patent published in 2017 - IPC C09K19/56 C09K19/02 G02F1/139 

FIELD: chemistry.

SUBSTANCE: method for obtaining a homeotropically oriented liquid crystal layer of a liquid crystal device (LC) is described. The method comprises applying to the LC substrate a cell of the formula (1) R_FR_F'QZ or R_FR_F"QZ (1), where R_f=R₁=C_nF_2n+1O-, , , , Q=CO or CS; Z=-NHR_H or -N(R_H)₂, where R_H alkyl C₁-C₆, Z=-NHR₃ or -N(R₃)₂, where R₃ alkyl C_kH_2k+1, k = 1-8, in a solvent, for example, in a cold solution 112. The substrate is soaked in a solution of the orientant (1), blasting, centrifugation, fixation of the layer of the orientant (1), and flushing of the loose coating are performed.

EFFECT: invention provides the most accurate homeotropic orientation of the liquid crystal of the LCD device, regardless of the structure of the orientator, the values of Q and Z, the orientation angle does not change and is 90 degrees.
