| Research Abstract |
To realize a novel mode liquid crystal(LC) devices, we have performed the development of fabrication processes of the photo-alignment layers that can generate a desired pretilt angle of LC molecules between 0°and 90°. By fabricating photo-alignment layers consisting of micrometer-size homogeneous and homeotropic alignment domains, we confirmed that the pretilt angle can be controlled by the domain area ratio. This result suggests the usefulness of the nano-domain patterned photo-alignment layers for controlling the pretilt angle. We proposed another fabrication method using amine vapor treatment, and succeeded in significantly extending the controllable range of the pretilt angle.
