Abstract

We present the alignment characteristics of liquid crystal (LC) molecules on solution-derived tin(iv) oxide (SnO2) films. Solution processing was used in place of the sputtering method to deposit SnO2 films as LC alignment layers. The LC molecules on the SnO2 surfaces could be homogeneously and uniformly aligned by ion-beam (IB) irradiation. X-ray photoelectron spectroscopy (XPS) analysis indicated surface reformation of the SnO2 films resulting from annealing and that IB irradiation affects the uniform LC orientation. Fast response times of twisted nematic cells constructed with IB-irradiated SnO2 films were observed, which indicates that the proposed IB-irradiated solution-derived SnO2 films have considerable potential for use in the production of advanced LC displays.
