PURPOSE:To make air bubbles for absorbing thermal expansion unnecessary and to obtain a high-quality ECD cell with high mass-productivity by deforming a substrate to discharge an electrolytic soln. by an amount corresponding to a calculated increase in the volume due to thermal expansion and by sealing an electrolytic soln. injecting hole in the deformed state. CONSTITUTION:The back glass substrate 14 of an ECD cell holding an injected selectrolytic soln. is bent with a rod 18 for pressurization to discharge the electrolytic soln. 19 corresponding to the soln. to be expanded during thermal expansion from the injecting hole 17. In consideration of mass-productivity, the amount of the electrolytic soln. to be discharged is controlled most suitably as follows: if the point of time when the rod 18 is brought into contact with the substrate 14 is considered to be 0 and the distance of movement of the rod 18 moved until the prescribed amount of the soln. is discharged is represented by L, L is prescribed by the internal volume of the ECD cell. By sealing the cell when the rod 18 is moved by the prescribed distance L, an ECD cell having a structure with an electrolytic soln. discharged by an amount corresponding to a previously calculated increase in the volume due to thermal expansion is formed. |
