ABSTRACT:
A film spacer is formed by individual spacers in strip form which a cover layer covers. To fabricate a liquid crystal cell using the film spacer, the spacer is cut longitudinally to partially form the strips and supported on one side of a lower glass panel. The spacer and panel are portioned to enable a liquid crystal path to be formed between each extending end of the strips and a sealant to be subsequently applied around the periphery of the one side of the lower glass panel. The individual spacers are separated by cutting the blank area from the film spacer at the ends of the strips. The cover layer is removed, while keeping the arrangement of a plurality of spacers and removing only spacers covering desired display areas of the lower panel. A sealant is then provided around the lower glass panel. An upper glass panel is sealed to the lower panel with the spacers inbetween, and liquid crystal is infused through the entrance.
