Abstract

A liquid crystal display panel including at least one transparent plate formed of plastic material including a barrier coating layer for reducing permeability of the resin plate to air and/or water vapor is provided. A transparent electrode is formed on the inner surface of the transparent plate. Transparent resin plates are desirable as they are optically clear for producing a clear display, light weight and sufficiently flexible to impart impact resistance to the display panel.
