Description of the Related Art An OLED layer is sandwiched between a pair of electrodes facing each other, and electrons are injected into the OLED layer from one electrode (cathode) and holes are injected from the other electrode (anode). As a result, the OLED device that emits light by combining electrons and holes in the OLED layer has advantages such as excellent visibility and various emission colors of organic substances forming the OLED layer. Therefore, for example, it is suitably used for displays and light sources for various information industrial equipment.

ED materials are generally susceptible to moisture, oxygen, etc., and when an OLED element is driven in the atmosphere, its light emitting characteristics deteriorate rapidly. Therefore, in the OLED element, the element itself is hermetically sealed and isolated from the atmosphere. In addition, the closed atmosphere is replaced with an inert gas or the like. Such a sealed structure is disclosed in, for example, Japanese Patent Application Laid-Open No. 9-148066 and Japanese Patent Application Laid-Open No. 10-275.
It is disclosed in Japanese Patent No. 679.

がある。However, this hermetically sealed airtight container has a laminated structure, and a UV curable resin is generally used for adhesion, because the space inside the airtight container has an inert gas. By repeating the heat generation of the OLED element and cooling after stopping, it will breathe from the adhesive resin part, and due to the nature of the resin, invasion of oxygen and moisture is inevitable over the years. Therefore, measures such as enclosing a desiccant are taken, but the life is only slightly extended. Also, the OLED device, which can be formed extremely thin, has a thick display due to the closed structure containing a desiccant. Further, since OLED elements are generally formed on a glass substrate by film formation, there is a problem in terms of impact resistance.
