• Alignment layers for liquid crystal cells were prepared by directional deposition of high molecular weight rigid-rod ionomers on glass and indium-tin-oxide substrates. Several deposition techniques were developed and tested. Material type, concentration, temperature, and application technique were systematically varied and the resultant alignment of the liquid crystals studied. Three different methods of applying the alignment layer were investigated: directional spray deposition, brushing, and directional deposition using a squeegee (doctor bar). The application temperature ranged from 30 to 80℃. The best results were obtained using a squeegee to perform directional deposition at temperature of less than 60℃. The alignment layers obtained in this way are robust, exhibit excellent alignment, and have pretilt angles of a few degrees. [DOI: 10.1143/JJAP.41.2183]
