Title:
ORGANIC ELECTROLUMINESCENT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2016/143660
Kind Code:
A1
Abstract:
The objective of the present invention is to provide an organic electroluminescent element which has excellent bending resistance enough to prevent separation of an element when bent, while having excellent sealing performance that is capable of suppressing the generation of a non-light-emitting portion even if stored in a bent state in a high temperature high humidity environment such as an environment at 60°C at 90% RH. This organic electroluminescent element 100 is provided with: a first gas barrier layer 12 that is laminated on a flexible base 11; a second gas barrier layer 13 that is laminated on the first gas barrier layer 12; a light emitting unit layer 17 that is laminated on the second gas barrier layer 13; and a covering layer 18 that covers the light emitting unit layer 17. This organic electroluminescent element 100 is characterized in that: the first gas barrier layer 12 is a polysilazane modification layer; and the second gas barrier layer 13 contains a metal oxide that contains a metal element selected from among V, Nb, Ta, Ti, Zr, Hf, Mg, Y and Al.
