Patent number: 9502680Abstract: To provide a light emitting device that has a structure in which a light emitting element is sandwiched by two substrates to prevent moisture from penetrating into the light emitting element, and a method for manufacturing thereof. In addition, a gap between the two substrates can be controlled precisely. In the light emitting device according to the present invention, an airtight space surrounded by a sealing material with a closed pattern is kept under reduced pressure by attaching the pair of substrates under reduced pressure. A columnar or wall-shaped structure is formed between light emitting regions inside of the sealing material, in a region overlapping with the sealing material, or in a region outside of the sealing material so that the gap between the pair of substrates can be maintained precisely.Type: GrantFiled: May 5, 2015Date of Patent: November 22, 2016Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Yoshiharu Hirakata, Shunpei Yamazaki
