ABSTRACT:
A common transfer contact is provided with such an electro-optical display cell as a liquid crystal display cell or an electrochromic display cell for electrically connecting an electrode disposed on a substrate to a terminal arranged on another substrate. The common transfer contact is encircled by a seal material. The seal material is so arranged on the substrate as to occupy a larger area at the portion where the common transfer contact is provided than the remaining portion. Further the seal material can have a desired number of notches where the seal material is removed to ensure ready placement of the common transfer contact. At least, the common transfer contact is pre-heated before forced toward the seal material so that organic solvent contained with the material of the common transfer contact be in part eliminated. The pre-heating process is carried out at a temperature of 60.degree.-70.degree. C. for a period of 10-20 minutes.
