Patent number: 7744949Abstract: A method of manufacturing a light emitting device of upward emission type and a thin film forming apparatus used in the method are provided. A plurality of film forming chambers are connected to a first transferring chamber. The plural film forming chambers include a metal material evaporation chamber, an EL layer forming chamber, a sputtering chamber, a CVD chamber, and a sealing chamber. By using this thin film forming apparatus, an upward emission type EL element can be fabricated without exposing the element to the outside air. As a result, a highly reliable light emitting device is obtained.Type: GrantFiled: December 4, 2008Date of Patent: June 29, 2010Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Toshimitsu Konuma, Hiroko Yamazaki

Patent number: 7744948Abstract: An electroluminescence device includes a tubular first electrode, an electroluminescence layer formed on an inner surface of the first electrode, and a second electrode formed on an inner surface of the electroluminescence layer. A method for manufacturing the electroluminescence device includes: causing the inner surface of the first electrode to be lyophilic with respect to an electroluminescence layer forming liquid; conducting the electroluminescence layer forming liquid into and out of the inside of the first electrode, thereby forming a liquid film of the electroluminescence layer forming liquid on the inner surface of the first electrode, which inner surface is lyophilic with respect to the electroluminescence layer forming liquid; and forming the electroluminescence layer by drying the liquid film of the electroluminescence layer forming liquid formed on the inner surface of the first electrode.Type: GrantFiled: July 25, 2006Date of Patent: June 29, 2010Assignee: Seiko Epson CorporationInventor: Naoyuki Toyoda
