发明名称 Curable composition, cured product, and organic electroluminescence element using same
摘要 Provided are: a curable composition containing a compound having a polymerizable group, which allows the production of an organic electroluminescent element in which a plurality of organic layers are formed between both electrodes to be performed through a wet process; and an organic electroluminescent element improved in light emission performance, including a layer containing a cured product of the curable composition. Specifically, provided are: a curable composition containing an indolocarbazole compound having one polymerizable group such as a vinyl group or an epoxy group and having an indolocarbazole skeleton, and a compound having two polymerizable groups; and an organic electroluminescent element including a layer obtained by applying and curing the curable composition as a hole transport layer of the organic electroluminescent element.
