Mechanical Stability of Pixel-Isolated Liquid Crystal Mode with Plastic Substrates

Abstract

We have fabricated a plastic liquid crystal display using the pixel-isolated liquid crystal (PILC) mode and characterized the mechanical stability of the sample against mechanical pressure and bending. Since the liquid crystal molecules are fully isolated in the pixels by the phase-separated polymer walls in the PILC mode, the electrooptic properties of the sample show good mechanical stability. In addition, a polymer layer formed on the upper substrate enhances the adhesion between two plastic substrates.
