Abstract: Ionomer resin sheet is stretched in one direction in the plane of sheet to give uniaxial anisotropy, and then heated above the melting point under pressure to cause relaxation of the anisotropy. After cooling, a sheet of biaxial anisotropy is obtained. The degree of anisotropy depends on the initial stretching, heating temperature, heating time and pressure.

Abstract: Disclosed is a liquid crystal display comprising a liquid crystal layer, a pair of substrates holding the liquid crystal layer therebetween and having two sets of crossed electrodes formed thereon, a pair of crossed polarizers provided outside the substrates and having polarization axes parallel to the electrodes respectively, and an orientation means for making the liquid crystal molecules orient to the intermediate direction of the crossed polarizers at the commencement of voltage application. The orientation means is selected form pretilt, fringe electric field, combinations thereof, etc. In the beginning of voltage application, no leakage light is generated even if the liquid crystal molecules are tilted by a fringe electric field in the vicinity of the edges of the electrodes.

Abstract: A method of manufacturing an optical compensator sheet comprising the steps of providing a sheet of ionomer, which ionomer is bridged with sodium or magnesium ions, stretching said sheet of ionomer along one direction in the plane of sheet, so as to generate uni-axial optical anisotropy of predetermined amount having an optical axis along the stretched direction, sandwiching said stretched sheet of ionomer between a pair of substrates, putting said sandwiched sheet in an evacuatable heat-resisting bag, evacuating and sealing said bag, loading said bag in an autoclave furnace and applying heat and pressure to said sheet in said autoclave furnace at a temperature not less than the melting point of the sheet. The stretched sheet has a positive optical anisotropy along the stretched direction. The sheet after heat and pressure treatment has a negative optical anisotropy along the normal to the sheet.

C. for at least about 30 minutes.

Abstract: When the reset input changes 0 V to Vcc, predetermined operational mode control information is set in an operational mode register (11) to establish a user operational mode. When the reset input changes from 0 V to 2 Vcc, the operational mode control information inputted to a predetermined terminal of the input/output port (25, 58) is set in the operational mode control unit (10a, 10b) to establish a test or other mode.
