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: 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: 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: 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: An organic EL display panel which does not impair a sealing effect and ensures a smooth edge portion when individual organic EL display panels are separated from a mother panel on which a plurality of organic EL display panels are formed is provided. A mother panel is formed by adhering a mother element substrate and a mother sealing substrate by way of an adhesive material sheet. In separating the mother panel into individual organic EL display panels, laser beams are radiated to the mother panel along separation lines so as to lower an adhesive strength of the adhesive material sheet at such portions. Thereafter, scribing is applied to the mother panel along the separation lines. Due to such a constitution, it is possible to realize an organic EL display panel without lowering a sealing effect and ensuring smooth appearance.

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.

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: The present invention provides a manufacturing method of a display device which can favorably cut a display panel having the structure where a resin layer is sandwiched between an element substrate and a sealing substrate. The manufacturing method of a display device includes the steps of: forming a display panel by sandwiching a resin which is hardened by any one of electromagnetic waves, radioactive rays and electron beams and heat between an element substrate having a display region in which a plurality of light emitting elements are formed and a sealing substrate in such a manner that the resin covers the display region; radiating at least one of electromagnetic waves, radioactive rays and electron beams to the display panel thus hardening first portions of the resin and leaving second portions of the resin in a state softer than the first portions; separating the display panel at positions corresponding to the second portions; and heating the separated display panel thus further hardening the resin.
