Definitions
- the present invention relates to a hot melt type member and an organic EL display panel.
- it relates to a sealing member for organic EL elements and an organic EL display panel using the same.
- it is a thin organic EL display that can maintain stable light emission characteristics without being affected by moisture or oxygen for a long period of time. This is related to an improved technology that enables mass production of panels with high reliability. Background art
- Organic EL elements are made of ITO (Indium Tin Oxide) transparent electrode (anode), organic film on a glass substrate.
- ITO Indium Tin Oxide
- anode organic film on a glass substrate.
- Organic hole transport layer, organic light emitting layer, etc. and a metal electrode (cathode) are formed.
- the organic film or the metal electrode is weak against moisture, oxygen, heat, or an organic gas (hereinafter, also referred to as “outgas”) that generates components.
- the organic EL element is placed in an atmosphere that excludes water and oxygen, the outgassing of component power is reduced as much as possible, and it occurs when the organic EL element emits light. It is necessary to prevent deterioration due to moisture, oxygen, heat, and outgas by adopting a structure that allows heat to escape efficiently.
- an organic EL element (anode 2, organic layer 3, cathode 4) is laminated on a substrate 1 such as glass as shown in FIG.
- a sealing cap 5 made of glass or metal is placed on the substrate 1 and bonded to the substrate 1 with a sealant 6 and sealed, and the organic EL element is sealed in a sealed container composed of the substrate 1 and the sealing cap 5.
- barium oxide (BaO) for capturing moisture, calcium carbonate (CaO), or sheet-like moisture scavenger 7 using these is encapsulated, and the dredging method is taken! / Speak.
- an organic EL display panel using such a moisture scavenger for example, a transparent electrode formed of a transparent electrode material on a transparent substrate surface, and an EL material laminated on the transparent electrode A light emitting layer, a back electrode laminated on the light emitting layer and formed to face the transparent electrode, a water repellent film covering the entire surface of the light emitting layer and the back electrode, and the light emitting layer together with the water repellent film
- a transparent electrode formed of a transparent electrode material on a transparent substrate surface, and an EL material laminated on the transparent electrode
- An organic EL element characterized by comprising an insulating protective member for sealing for sealing.
- Patent Document 1 JP 2000-68047 A
- powdery BaO or CaO that is a moisture scavenger or a sheet-like material using these is used for a sealing cap 5 that seals the organic EL element on the substrate 1.
- a water scavenger 7 is to be provided.
- the thickness of the sealing cap 5 is required to be 0.7 to 1.0 mm, and there is a problem that the thickness of the organic EL display panel is increased.
- the sealing cap 5 when the size of the light emitting part is increased, the strength of the organic EL display panel is reduced because the sealed container has a hollow structure. There is a problem that 5 becomes easily bent and may come into contact with the cathode, and the reliability as a light emitting element is lowered.
- Patent Document 1 discloses that a water repellent film having a single component force such as wax, fluorine-based water repellent, silicon-based water repellent is formed on an organic EL element. The purpose is to prevent adhesion and to deteriorate the organic EL element.
- a moisture scavenger use particles with a relatively large particle size of 100 to 500 / ⁇ ⁇ , or sprinkle the particles after forming a water-repellent film. It is not mainly about formation.
- an organic EL display panel that uses a moisture scavenger and is thin is considered.
- Patent Document 1 since a relatively large particle size of 100 to 500 ⁇ t ⁇ ⁇ ⁇ is used as a powder, it cannot be used in an actual process. There's a problem.
- Patent Document 1 since the water repellent layer is formed by vapor deposition of wax, depending on the wax used, the performance of the organic EL element may be degraded by the evaporated wax.
- the main object of the present invention is to overcome the above-mentioned problems.
- the present invention relates to the following hot-melt type member and organic EL display panel.
- a hot-melt type member containing a moisture scavenger and wax.
- the hot-melt member according to item 8 wherein the electronic device is an organic EL display panel, an organic solar cell, or an organic semiconductor. 10. A transfer film in which the hot-melt member according to item 1 is laminated on a releasable substrate
- An organic EL display panel including 1) a substrate, 2) an organic EL element formed on the substrate, and 3) a casing for sealing the organic EL element, wherein the organic EL element and the casing An organic EL display panel in which the hot-melt member according to claim 1 is disposed therebetween.
- the hot melt type member of the present invention has hot melt properties, it has an arbitrary thickness and pattern on a casing (hereinafter also referred to as "sealing casing") or an organic EL element.
- a hot-melt member layer containing a moisture scavenger that is in close contact with the organic EL element can be formed, and outgassing is also suppressed, so that the effects of moisture, oxygen, and outgas are affected over a long period of time. It is possible to provide an electronic device (for example, an organic EL display panel) that can maintain stable light emission characteristics.
- the hot melt type member of the present invention can alleviate or eliminate problems such as cracks.
- the form is a powdery inorganic oxide or organometallic compound (including organometallic complexes, such as BaO and CaO) having a small particle diameter, or a sheet form using these ( (Thin film) Thickness with recesses to use hot melt members!
- organometallic complexes such as BaO and CaO
- the thickness of the organic EL display panel can be reduced by disposing the hot-melt type member of the preferred form of the present invention without a gap between the substrate and the sealing casing. It is possible to cope with an increase in size without any problem.
- a transparent wax is selected as the wax of the present invention
- a transparent thin film layer having a moisture trapping function can be provided on the cathode by combining with a transparent moisture trapping agent.
