Abstract

We proposed a new method of enhancing the stability of a liquid crystal (LC) mode for flexible display applications. In the device, LC molecules are isolated in pixels where LCs are surrounded by a microstructure produced by a stamping method with a durable elastomer such as poly(dimethylsiloxane) (PDMS). Two substrates are tightly attached by a solidified polymer layer produced by anisotropic phase separation from LC/polymer composites. The electrooptic characteristics of our sample are comparable to those of a normal sample without a PDMS microstructure. This method can be applicable to the fabrication of large plastic LCDs using a roll-to-roll process.
