PURPOSE: To seal continuously a liq. crystal material without forming bubbles and to attain high productivity by laminating the 1st and the 2nd flexible transparent insulating film and applying a pressure at a prescribed temp.
CONSTITUTION: Polyethylene terephthalate films 2a, 2b as flexible transparent insulating films are fed from rolls 102a, 102b, and a thermosetting adhesive 3 is printed on the film 2a with a printer 103 in the form of a prescribed pattern. a liq. material contg. glass fibers as spacers 4 is printed on the film 2b with a printer 104, and the films 2a, 2b are oriented through heating furnaces 105. A liq. crystal material 5 is dropped on the film 2b from a liq. crystal dropping device 106, and by laminating the films 2a, 2b with the 1st rolls 201 of a heat roll device 107, an excess of the material 5 is pressed out to eliminate residual bubbles. The films 2a, 2b are adhered to each other by heating with the 2nd rolls 211 and fixed by cooling with the 3rd rolls 221.
