High Quality Ferroelectric Liquid Crystal Display with Quasi-Bookshelf Layer Structure

We realized a surface stabilized ferroelectric liquid crystal display with high contrast ratio and high transmittance using a conventional rubbing method. Such remarkable electrooptical properties are based on the switching between uniform states in a cell treated with an AC electric field in the SmC*. It was confirmed by X-ray diffraction that the treatment caused a permanent change in the smectic layer structure from a chevron to a quasi-bookshelf structure. An example of multiplexing is also displayed.
