Abstract: A mother element substrate and a mother seal substrate are adhered with each other via an adhesive sheet. An adhesive sheet cut portion of the adhesive sheet corresponding to a terminal portion is formed at a time when the adhesive sheet is applied to the mother seal substrate, thus requiring no processing of the terminal portion afterward. Since the adhesive sheet cut portion extends to reach an edge of the adhesive sheet to prevent deformation of the adhesive sheet around the terminal portion after adhering the mother element substrate and the mother seal substrate with each other under the negative pressure so as to be returned to the atmosphere, thus realizing the solid seal type organic EL display device with high reliability.

Abstract: A sealing substrate is arranged to oppositely face an element substrate on which organic EL layers are formed in a matrix array with a sealing material sandwiched therebetween. A gel-state desiccant is filled in an inner space surrounded by the element substrate, the sealing substrate and the sealing material. Since the gel-state desiccant is in a gel state, the gel-state desiccant is flexibly filled in the inner space of the organic EL display device thus completely eliminating a gap. Since the inner space is filled with the gel-state desiccant, moisture hardly intrudes into the inner space from the outside and, at the same time, a mechanical strength of the organic EL display device is also enhanced.

Abstract: A sealing method of an organic EL display device which can effectively prevent the organic EL display device from being influenced by moisture and can suppress the manufacturing cost of the organic EL display device is provided. An organic EL element is covered with a resin sheet. The resin sheet is adhered to a sealing substrate and an element substrate on which organic EL elements are formed by lamination. At a peripheral portion of the organic EL display device, between the element substrate and the sealing substrate, an organic seal is filled to a side portion of the resin sheet using an under-filling method, and the organic seal is cured by radiating ultraviolet rays. Due to such constitution, it is possible to realize the highly reliable sealing of the organic EL display devices at a low cost.

Abstract: A manufacturing method of an organic EL display device which can suppress a manufacturing cost while effectively preventing organic EL layers from being influenced by moisture is provided. An organic EL element is covered with a resin sheet. The resin sheet is adhered to a sealing substrate and an element substrate on which organic EL elements are formed by lamination. Laser beams are radiated to a terminal portion formed on the element substrate so as to generate impact waves in the terminal portion by laser beams thus removing the resin sheet from the terminal portion. Thereafter, edge portions of the sealing substrate and edge portions of the resin sheet are removed along a line a. Due to such steps, it is possible to manufacture highly reliable organic EL display devices at a low cost.

Abstract: A bonding agent sheet (30) including removed bonding agent portions (31) corresponding to terminal portions (102) is bonded to a mother sealing substrate (400). Further, a mother element substrate (100) including display regions (101) and the terminal portions (102) is bonded to the bonding agent sheet (30) to form a mother panel (200). Then, the mother panel (200) is separated into individual organic EL display panels to form organic EL display devices.

Abstract: An organic EL element section (1000) is formed on a circuit formation section (102) formed on a circuit board (101). The organic EL element section (1000) is covered with a protective layer (113) including an SiNxOy film. The SiNxOy film has infrared absorption characteristics including: an Si—O—Si stretching vibration absorption peak appearing at energy lower than 1,000 cm?1; an absorption intensity of an Si—N stretching vibration absorption peak appearing in the vicinity of around 870 cm?1 which is 0.75 or more times an absorption intensity of the Si—O—Si stretching vibration absorption peak; and an absorption peak intensity in a range of 2,000 to 4,000 cm?1, which is 5% or less of the absorption intensity of the Si—N stretching vibration absorption peak. Thus, the protective film having an excellent moisture-blocking property may be obtained, and life property of an organic EL display device may be improved.

Abstract: An object of the present invention is to provide a bottom emission type organic EL display device that has a light-emitting element unit thereof protected from being damaged by a stored desiccant, that has a long service life, and that exhibits excellent display characteristics of a high luminance and a high contrast. The solution is such that the organic EL display device includes a desiccant assembly which is disposed on the internal side of a sealing substrate and which has a cushioning member thereof jutted out of the surface of a desiccant.

Abstract: There is disclosed a construction which facilitates preventing of organic electroluminescence films from being broken by contact between desiccant members and the organic electroluminescence films which are provided inside an organic electroluminescence display device. Organic electroluminescence films are formed on a substrate An interior of an organic electroluminescence display device is sealed by a rear glass plate which is sealingly bonded to the substrate. The rear glass plate has recess portions in which desiccant members are mounted by double-side adhesive tapes. Thick portions are provided between respective adjacent recess portions of the rear glass plate, whereby the rear glass plate is prevented from being made to flex, and contact between the desiccant members and the organic electroluminescence films formed on the substrate is prevented.
