Abstract

In a conventional liquid crystal display (LCD), glass substrates coated with an indium tin oxide (ITO) layer are typically used for the application of an electric field to the liquid crystal material. For many applications, there is a need for a LCD with a plastic substrate. While ITO works well with glass, it does not adhere as well to plastic. It is brittle, and has a tendency to crack under constant bend conditions. Polypyrrole is well known for its good conductivity and chemical stability. Moreover, as an organic polymeric material, polypyrrole film can also flex and bend with the plastic substrate. Therefore, it is a good candidate for plastic LCDs. We present here the results on the development of polypyrrole films deposited on plastic substrates which are suitable for reflective LCDs.
