Abstract

We have developed a ferroelectric liquid crystal device with a novel structure containing a polymer fiber network for flexible light-weight displays using thin plastic substrates. The aligned polymer fibers of sub- μ m-diameter were formed under ultraviolet light irradiation in a heated nematic-phase solution consisting of liquid crystal and monofunctional acrylate monomer. The rigid polymer network was found to adhere to the two plastic substrates, and the uniform liquid crystal alignment provided a contrast ratio of 100:1 for a monomer concentration of 20 wt%. This device achieves a continuous grayscale capability as a result of change in the spatial distribution of small liquid crystal domains, and also exhibits a fast response time of 80 μ s due to high-purity separation of polymer and liquid crystal materials. It therefore has attractive features for flexible moving-image display applications.
