Abstract
An improved simple and cheap method of forming electrode connector for liquid crystal display device has been found. This novel method eliminates difficulties in complicated compression molding process required a high accuracy of dimensions in a molded electrode connector. This method comprises the four steps of (A) printing a plurality of parallel conductive strips with a predetermined width and interval for the electrode connector on one side of a sheet of flexible polyester film with a special suspension ink and drying the printed ink on said polyester film, (B) applying a hot-setting adhesive suspension all over the other side of said polyester film by spraying or printing process, and drying a thin layer of said adhesive suspension on said polyester film, (C) cutting a rectangular piece having the desired size out of the resulting film having an adhesive coating layer on the surface in the step (B), and (D) putting a length of film with the adhesive layer coated on the upper side thereof on a flat plate heated at the temperature of 100.degree.-200.degree. C., and rolling a rubber tube having a small diameter on said film in the direction of said vertical strips printed on the lower side so as to adhere said film around said rubber tube. Furthermore, this method comprises the five steps of the above-mentioned (A), (B), (C), (D), and (E) laterally hot-pressing said cylindrical electrode connector obtained in the step of (D) on a hot plate heated at the temperature of 100.degree.-200.degree. C. so as to mold into a cylindrical electrode connector having a desired thickness in an elliptic section by using a thickness gauge.
