Abstract

PURPOSE: To assure and stabilize the conduction between an electrode terminal and a connector and to improve reliability by applying solder by dipping on an Ag layer formed on the electrode terminal and further slightly polishing the solder layer to flatten the surface.
CONSTITUTION: Ag paste is printed on the electrode terminal 4 prior to the assembly of a cell and is calcined, for example, for 10 minutes at 500°C to form the Ag layer 5 at the time of producing an LCD 1. One side end of a lower glass substrate 3 is dipped into a solder tank after the assembly of the cell and is pulled up at a prescribed speed to form the solder layer 6 on the Ag layer 5. The solder layer obt. in such a manner is built up by surface tension and, therefor, the surface is polished by 1 to 2μm and is thereby flattened after the dipping. The contact stability of the solder layer 6 and a contact point part 11a of the connector 10 is improved in this way and the insertion of the connector 10 to the LCD 1 is facilitated. The damage of the glass substrate at the time of insertion of the connector is thus averted.
