Problems solved by technology

However, the resistance of organic EL elements to moisture is very weak, and there are following problems: the light-emitting material (light-emitting layer) is deteriorated due to moisture, and the brightness is lowered, or it does not emit light, or the interface between the electrode and the light-emitting layer is damaged due to moisture. peeling occurs due to the impact, or the metal oxidizes and becomes a high resistance

Embodiment 2

[0150] Instead of synthetic fluorphlogopite (plate-shaped filler; PDM-5B, manufactured by TOPY Industry Co., Ltd.), a plate-shaped glass filler (FTD010-F01, manufactured by Nippon Plate Glass Co., Ltd.) was used, except that, using the same method as in Example 1, A varnish and a resin sheet of the resin composition are produced.

Embodiment 3

[0152] A varnish of the resin composition was prepared in the same manner as in Example 1, except that the amount of synthetic fluorphlogopite (plate-like filler; PDM-5B, produced by TOPY Industry Co., Ltd.) was changed from 100 parts to 50 parts. and resin sheets.

Abstract

The present invention provides a resin composition which is capable of exhibiting higher moisture shielding properties, thereby being suitable for the formation of a sealing part of a light emitting element such as an organic EL element, an optical semiconductor such as a high luminance LED, a light-receiving element such as a solar cell, and the like. The resin composition contains the components (A)-(C) described below: the component (A): a thermoplastic resin, the component (B): a moisture-absorbing filler, the component (C): a plate-like filler, and has a moisture content of 1,500 ppm or less.

Description

technical field [0001] The present invention relates to a resin composition and a resin sheet, and relates to a resin composition and a resin suitable for sealing electronic components, especially light-emitting components such as organic EL (Electroluminescence) components, optical semiconductors such as high-brightness LEDs, and light-receiving components such as solar cells. Sheet. Background technique [0002] An organic EL element is a light-emitting element using an organic substance as a light-emitting material, and has attracted attention in recent years because it can obtain high-intensity light emission at a low voltage. However, the resistance of organic EL elements to moisture is very weak, and there are following problems: the light-emitting material (light-emitting layer) is deteriorated due to moisture, and the brightness is lowered, or it does not emit light, or the interface between the electrode and the light-emitting layer is damaged due to moisture. Peel...
