Polymer packaging material for liquid crystal cell

摘要: A twisted nematic liquid crystal material is sandwiched between two electrode carrying polymer film or sheet substrates in a display assembly. The substrate preferably semi-crystalline aromatic heterochain characterized by glass transition point (T g ) of at least 90° C. and devoid secondary transitions the -50° to +80° range. crystallinity controlled so that crystallite size substantially smaller than wave length visible light (350-750 micrometers). In preferred embodiment, an optically isotropic top formed amorphous cast thermosetting acrylic resin lower flexible polymer.
