Embodiment 1

[0132] In Example 1, 35 parts of CEL2021P, 10 parts of CEL2081, 1 part of CPI410B, 55 parts of HXO, and 0.5 part of F554 were mixed under atmospheric conditions to prepare curable composition 1. Except having used each component of the kind and compounding quantity shown in Table 1, it carried out similarly to Example 1, and prepared curable composition 2 - curable composition 20.

[0134]

[0135] A plurality of array substrates were prepared. The array substrates had: a glass substrate ("OA-10" manufactured by NEC Glass Co., Ltd.) on which ITO transparent electrodes were formed in an array; and only a part of the ITO transparent electrodes. A planarization layer with a film thickness of 3 μm for exposed contact holes.

[0136] An Al film with a film thickness of 100 nm was formed on the planarization layer by a direct current (DC) sputtering method using an Al target. An ITO film with a film thickness of 20 nm was formed on the Al film by the DC magne...

Abstract

The invention relates to curable composition, a cured product, a light emitting device and a manufacturing method for the same. The invention provides a curable composition which can be coated on an object and is excellent in moisture expansion and even in film forming, and air escape is small after hardening. The curable composition comprises a polymerized compound under 20 DEG when a vapor pressure does not reaches 0.1kPa, (B) polymerization initiator and (C) a compound having at least one of the polymerized base and a reaction base of the compound, wherein the saturated vapour pressure is 0.1kPa-20kPa. Relative to the 100 weight parts of the compound A, the content of the compound is 35-1200 weight parts.

Description

technical field [0001] The present invention relates to a curable composition, a cured product, a light emitting device and a manufacturing method thereof. Background technique [0002] In order to protect an object or the like with a cured product, various curable materials have been proposed as a curable composition for forming a cured product. For example, an organic electroluminescence (EL) element having a laminated structure including an anode, an organic light-emitting layer, and a cathode is known as one of elements for light-emitting devices developed in recent years. However, since the light-emitting material contained in the organic light-emitting layer is easily degraded by moisture and oxygen, it is necessary to seal the organic EL element (for example, refer to Patent Document 1). Therefore, in order to protect the organic light-emitting layer, device sealing using a curable composition is known. [0003] [Prior art literature] [0004] [Patent Document] ...
