Abstract
Techniques for successively fabricating liquid crystal cells at low cost, using two resinous substrates wound on their respective rolls. A color filter and an electrode pattern are formed by printing techniques. Furthermore, an orientation film is printed. These manufacturing steps are carried out successively by rotating various rolls.
Claims14
A system for successively fabricating liquid crystal cells comprising:
- first winding means for winding a first flexible substrate;
- second winding means for winding a second flexible substrate;
- first transferring means for transferring said first substrate drawn out of said first winding means in a first direction;
- second transferring means for transferring said second substrate drawn out of said second winding means in a second direction;
- third winding means for winding a base film;
- means for forming color filters on said base film drawn out of said third winding means;
- means for forming a protective film on said color filters;
- means for forming an adhesive film on a rear side of said base film,
- means for sticking said first substrate to said base film via said adhesive film;
- means for forming at least a liquid crystal material for said first substrate;
- means for forming at least an electrode pattern for said second substrate;
- means for bonding said first substrate and second substrate to form a substrate assembly, said liquid crystal material and said electrode pattern facing each other;
- and
- means for cutting said substrate assembly to form a plurality of liquid crystal cells.
