Document Type and Number:
WIPO Patent Application WO/2019/188812
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a sealant for an organic EL display element that exhibits excellent coating properties with respect to a substrate or an inorganic material film even when formed into a thin film.
The present invention provides a sealant for an organic EL display element that contains a curable resin and a polymerization initiator. When, with respect to an SiO2 substrate having a surface free energy of not less than 70 mN/m and not more than 80 mN/m and an SiN substrate having a surface free energy of not less than 50 mN/m and not more than 60 mN/m, 10 pL of the sealant for an organic EL display element is dropped from the height of 0.5 mm from the substrate using an inkjet ejection device under the condition of 25°C and a frequency of 20 kHz, the diameter of the droplet one minute after the dropping is not less than 150 μm in each case.
