Description

Composition for sealing
Technical field
The present invention relates to can be sealed against in the case where not damaging organic EL element, to prevent caused by moisture The composition for sealing of deterioration.The Japanese Patent Application 2015-239493 that the application is filed an application based on December 8th, 2015 in Japan It number claims priority, and its content is incorporated herein.
Background technology
Organic electroluminescent (in the present specification, also referred to as " organic EL ") element has to be sandwiched using a pair of of opposite electrode The structure of luminescent layer, the electrode injection electronics from side, the electrode injection hole from the other side.The injected electrons and hole In luminescent layer in conjunction with when generate shine.The light extraction mode of organic EL element include top emission type and bottom emission type this two Kind, the aperture opening ratio of top emission type is big, therefore light extraction efficiency is excellent, is preferred in this regard.Including organic EL element Organic EL device it is aobvious as the tablet of full color due to the diversity of its high-impact, visibility and illuminant colour Show device or receives expectation as the equipment for substituting LED.
However, compared with other electronic units, organic EL element is easier to be influenced by moisture, and existing can be because immersion has Moisture in machine EL element and the problem of cause the oxidation of electrode, the denaturation of organic matter etc., the characteristics of luminescence caused to be remarkably decreased.Make For the method for solving the problems, such as this, it is known to utilize the side on the periphery of the excellent resin seal of moisture resistance (or cladding) organic EL element Method.
As above-mentioned encapsulating method, it is known to:Periphery to being formed in the organic EL element on substrate utilizes, and there is meeting to exist The lower composition for sealing that cured property occurs of UV irradiations is filled, and then cures above-mentioned composition for sealing, thus The method (1) being sealed;To composition for sealing of lid (lid) coating with above-mentioned property and after carrying out UV irradiations, by it Fit in the substrate for being formed with organic EL element and the method (2) being sealed.
The above method (1) is due to making organic EL element be directly exposed in UV, thus presence causes the characteristics of luminescence to reduce Problem.In addition, configuring colour filter on the top of organic EL element to form the organic EL device with high contrast In the case of, can because colour filter there are due to shield UV, therefore existing causes what the solidification of composition for sealing became inadequate to ask Topic.
On the other hand, in the above method (2), although can prevent due to making organic EL element be directly exposed in UV The caused characteristics of luminescence reduces, but since the solidification of composition for sealing under uv illumination can carry out rapidly, if presence is pasted Closing operation is slow, can cause fitting become difficult, yield rate reduce the problem of.
Following the description has been recorded in patent document 1:Containing epoxide, polymerization initiator and as cure retarder Crown ether, polyethers composition for sealing, even if with that can carry out and complete cured if shielding UV reactions after UV irradiations Therefore characteristic if using above-mentioned composition in the above method (2), can inhibit the organic EL element caused by UV Deterioration while realize sealing.It can decompose in the presence of cation however, crown ether, polyethers exist and generate exhaust, And the problem of causing organic EL element to deteriorate because of the exhaust.
