Application of photo-alignment technique for low pretilt angle liquid crystal cell
The photosensitive PI film composing of DOCDA/DAP-Chalcone [5-2,5-dioxotetrahydrofuryl]-3-methyl-3-cyclohexene-1,2-dicarboxylic anhydride/1,4-diaminophenol/4-n-propyl-4-(3-propylene hydroxide) chalcone] induces orientation of liquid crystal alignment perpendicular to the polarization direction. The pretilt angle of liquid crystal was about 1 degrees. It will be applied to the ferroelectric liquid crystal display.
