Problems solved by technology

like Figure 6A and Figure 6B As shown, in the case where the sealing material 901 is locally heated and melted in a state where it is difficult to secure the adhesiveness between the sealing material 901 and the glass substrates 912 and 913, compared with the case where the sealing material 901 is generally heated, the sealing material Poor leveling action
Therefore, it is easy to cause poor joints and cracks

Embodiment Construction

[0021] Embodiments of the present invention will be described below with reference to the accompanying drawings. Although a container used as an airtight container in an image display device such as FED, OLED, PDP, etc. will be described below, the airtight container of the present invention is not limited to them and can be applied to all containers that are airtightly sealed . As an example of such an airtight container, there is a vacuum insulated glass container.

[0022] In particular, the manufacturing method of an airtight container according to the present invention can be suitably applied to the manufacturing method of a container having a pressure-reduced inner space. In an image display device such as an FED having a depressurized internal space, a joint strength that can cope with the atmospheric pressure caused by the negative pressure of the internal space is required. However, according to the method of manufacturing an airtight container in the present invent...

Abstract

The invention relates to a hermetic container and a manufacturing method of the same. Adherence between a sealing material and a glass substrate is assured, thereby improving airtightness of a hermetic container. A manufacturing method of the hermetic container has: an assembling step of sealing a first glass substrate and a second glass substrate through a circumferential sealing material having plural straight line portions and plural coupling portions which connect the plural straight line portions so as to define an internal space between the first glass substrate and the second glass substrate; and a sealing step of maintaining the internal space to a negative pressure to an outside after the assembling step, applying such local force as to compress the coupling portions of the circumferential sealing material in a thickness direction of the sealing material, and heating and melting the sealing material by irradiating local heating light to the sealing material, to seal the first glass substrate and the second glass substrate.

Description

technical field [0001] The present invention relates to a method of manufacturing an airtight container, and more particularly, to a method of manufacturing an airtight container for an image pickup device having an electron-emitting device and a fluorescent film inside which are respectively kept in a vacuum state. Background technique [0002] Flat panel type image display devices such as organic LED displays (OLEDs), field emission displays (FEDs), plasma display panels (PDPs), etc. are well known. Each of these image display devices is manufactured by sealing glass substrates facing each other to form an internal space, and has a container that partitions the internal space from the external space. In order to manufacture such an airtight container, a space defining member, a partial adhesive, etc. are arranged as necessary between facing glass substrates, a sealing material is arranged in a frame shape for peripheral portions of the glass substrates, and sealing process...
