We propose optical phase-control devices using a liquid crystal (LC) material without applying a voltage, and demonstrate a composite alignment of LC molecules on a substrate with a patterned photo-resist film, where LC molecules are partly aligned parallel and perpendicular directions divided into very small areas on the substrate. The patterned film such as randomly distributed circular areas of small diameter size is fabricated by using a photo-mask and a photolithography technique. The LC cells are prepared using the locally composite alignment substrate and a perpendicular alignment substrate. The optical phase of the transmission light through the different pattern density regions was measured. Then, it is found that the optical retardation of the higher pattern density region is larger than that of the lower one.© (2005) COPYRIGHT SPIE--The International Society for Optical Engineering.
