Abstract
A method of controlling the alignment of a ferroelectric liquid crystal without the need of an alignment process, such as a rubbing process and a photo alignment process, in a liquid crystal display using a ferroelectric liquid crystal. The method uses a columnar alignment layer having a column structure with a plate-like molecule having photo dichroism in the visible light range as one of the alignment layers for controlling the alignment of the ferroelectric liquid crystal. The method forms a reactive liquid crystal layer produced by fixing a reactive liquid crystal including a polymerizable liquid crystal material on the side to be contacted with the ferroelectric liquid crystal on the columnar alignment layer, showing the nematic phase on the columnar alignment layer.
