Abstract
We propose a liquid crystal (LC) alignment method that can align LC molecules homogeneously on ion-beam-exposed indium–tin-oxide (IB-ITO) surface without coating alignment layer. To achieve high quality alignment conditions, the ion beam exposure energy and time have been found to be in the range from 50 to 1500 eV and from 1 to 300 s, respectively. On the IB-ITO surface treated under these conditions, a groove pattern is formed to be parallel to the ion beam exposure direction and optical anisotropy is induced to be parallel to the groove pattern, which causes the LC molecules to align. Moreover, thermal stability is ensured by baking the IB-ITO surface, due to effects such as an increase in polar anchoring energy. According to this method, the coating process of alignment layer is eliminated as well as alignment material is saved, which reduce fabrication cost.
