Abstract
A liquid crystal display device is made with plastic substrates (#1) and has an isotropic, non-birefringent polynorbornene alignment layer (#4) formed over an electrode pattern (#2). This isotropic, non-birefringent polynorbornene alignment layer also functions as a moisture barrier to prevent degradation of the liquid crystal fluid. No additional moisture barrier layers are needed.
