Document Type and Number:
WIPO Patent Application WO/2020/129794
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a curable resin composition which exhibits excellent curing properties by light having a long wavelength, which is excellent in terms of low out-gassing, and which can suppress display defects in an organic EL display element. The purpose of the present invention is also to provide a cured product of the curable resin composition; and an organic EL display element having the cured product. The present invention is a curable resin composition which can be used as a sealing agent for an organic EL display element and which contains a curable resin, a photopolymerization initiator and a sensitizer. The sensitizer contains an anthracene compound having an ester bond. When a cured product of the curable resin composition is subjected to thermal desorption GC-MS analysis for 30 minutes at 110ºC under thermal desorption conditions, the amount of anthraquinone quantitatively determined is 300 ppm or less in terms of toluene.
