MANUFACTURE OF LIQUID CRYSTAL DISPLAY ELEMENT

摘要

PURPOSE:To form continuously liq. crystal display elements after sealing and press bonding at peripheries and to obtain efficient manufacturing stages by forming two long-sized plastic films so that the axes of polarization meet at right angle to each other. CONSTITUTION:A long-sized polarizer of a PVA-iodine system is adhered to a polyether sulfone film so that the longitudinal directions coincide with each other. The 1st long-sized film 2 is obtd. The axis of polarization of the film 2 is parallel to the minor side direction of the film. Other polarizer is cut with the intervals equal to the width of a film and adhered to the film so that the axis of polarization is made parallel to the major side direction of the film. The 2nd long-sized film 1 is obtd. The film 1 is superimposed on the film 2 to form continuously liq. crystal display elements. When the long-sized films united to one body so that the axes of polarization meet at right angle with each other is used, the productivity can be improved because the films are continuously sent to a heating furnace.
