Abstract
This organic electroluminescent element sealing composition contains an addition reaction curing type silicone composition which is liquid at normal temperature and has a curing temperature of 100 degrees C. or below and a moisture content of 400 ppm or less. The addition reaction curing type silicone composition contains (A) polyorganosiloxane having an average of 0.2 to 5 alkenyl groups bonded to silicon atoms in one molecule, (B) polyorganohydrogensiloxane having at least two or more hydrogen atoms bonded to silicon atoms in one molecule, and (C) a platinum-based catalyst. The organic electroluminescent element sealing composition can prevent deterioration of the organic electroluminescent element and can provide the organic light-emitting device having a good light-emitting property for a long period.
