A vertically-aligned nematic liquid crystal cell was explored using photoirradiated thin films of a polymethacrylate with mesogenic moieties of 4-trifluoromethoxyazobenzene as side chains. The azobenzene-containing polymer films, providing high pretilt angles, were prepared by slantwise photoirradiation with non-polarized ultraviolet light, followed by an annealing treatment. The liquid crystal cell fabricated with the aligning films exhibited electrooptical properties with excellent optical quality on applying voltages even after heating at 100 °C for several hours.
