Patent ID: 7101244

Claim:
A method for manufacturing an airtight container having a space in which a pressure is lower than an outside pressure, between opposing first and second substrates, comprising steps of: assembling the container having a space between the first substrate on which an electrode is disposed on a surface to be facing the space and the second substrate which has a structure for supplying a potential to the electrode; and applying a pressure difference between inside and outside of the container assembled in the assembling step, wherein in the container before the applying step, the structure has a concave portion which is opened to an external atmosphere at a through-hole penetrating the second substrate and closed at a bottom of the concave portion, having electrical conductivity, and wherein the pressure difference is brought in the applying step to elongate lengths of the structure in a direction in which the first and second substrates are opposed to each other, whereby the structure is formed in a shape to enable supplying of a potential to the electrode through the bottom of the structure.
