Abstract
In an organic electroluminescence device (100), a hole transport layer (22) is formed of a cured resin obtained by a ring opening polymerization of a polymerizable compound (a) containing a ring opening polymerizable group in the presence of a polymerization initiator (b). In addition, both of a maximum peak height Rp and a maximum valley depth Rv in an upper surface of the hole transport layer (22) are less than or equal to 14 nm. Accordingly, an organic electroluminescence device having excellent mass productivity and high luminescent efficiency is realized.
