Abstract:
1. A method for making a liquid crystal display with wide viewing angle comprising: depositing first and second conductive electrodes and homeotropic aligning layers on facing surfaces of flat parallel substrates, each of the electrodes on a respective one of the facing surfaces, the first conductive electrode including a plurality of electrode sections; filling the space between the first and second conductive electrodes with nematic liquid crystal possessing negative dielectric anisotropy wherein connecting alternating ones of the electrode sections of the first conductive electrode to electric field generating potentials of opposite polarity as referenced to an electric field potential applied to the second conductive electrode generates a non-uniform electric field that orients molecules of the liquid crystal in the space between the first and second conductive electrodes, the electric field having components parallel to the plane of the substrates having various directions.
