Summary:Electro-optical Properties of liquid crystal displays of the twisted nematic field effect type (TN-FEM) have been systematicaly studied. It has been clarified that in application to display devices the vital points are; (1) removing the disclinations which result from the degeneration of alignment for the purpose of giving a certain view-angle to the devices ; (2) the view angle should be directed to the observer. In the multiplex driving scheme of the TN-FEM devices, the response properties (both τr and τd) are proportional only to η/κ (viscosity/elasticity), so the liquid crystal system should be selected by a different criteria from those of the static driving scheme.
