Fabrication of Single Substrate Flexible Twisted Nematic LC Cell Using a Photo-Polymer Cover Film

초록

A single substrate flexible display was fabricated by laminating a thin cover film of UV curable photo-polymer on the plastic bottom substrate. The micro-walls of photoresist on the bottom substrate are tightly bound with the cover film to provide the solid mechanical support for preserving the molecular alignment of liquid crystals (LCs). The ability of aligning LCs is induced by rubbed alignment layer on the bottom substrate and micro-grooves formed on the photo-polymer film. We demonstrated a twisted nematic LC mode on the plastic substrate with in-plane switching electrode. The fabrication process and electro-optical characteristic of the device are described.
