摘要:
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.

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.

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.

An organic electroluminescence device which can prevent the deterioration thereof attributed to moisture by preventing a desiccant from influencing organic electroluminescence elements is provided. The organic electroluminescence device includes: first and second substrates which are arranged to face each other in an opposed manner with a gap therebetween; organic electroluminescence elements which are formed on a first surface of the first substrate which faces the second substrate in an opposed manner; a desiccant which is formed on a second surface of the second substrate which faces the first substrate in an opposed manner; and a resin which is adhered to the first and second surfaces and covers the desiccant and the organic electroluminescence elements. The desiccant includes a portion which is arranged outside a region of the second surface which faces the organic electroluminescence elements in an opposed manner and surrounds the whole of the region, and the organic electroluminescence elements are isolated from the desiccant by way of the resin.

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.

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.

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.
