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.
