Provided are a curable composition for an organic electroluminescent element, which has high light emission efficiency and is applicable to a wet process, a cured product thereof, and an organic electroluminescent element containing the cured product in an organic layer. More specifically, provided are a curable composition containing a compound represented by an indolocarbazole skeleton compound, a cured product obtained by curing the curable composition, and an organic electroluminescent element containing the cured product in an organic layer. |

1. An organic electroluminescent element, comprising organic layers between an anode layer and a cathode layer laminated on a substrate, wherein at least one of the organic layers contains a cured product obtained by curing a curable composition containing 5 to 100 mol % of a compound represented by the general formula (1) and 0 to 95 mol % of a compound represented by the general formula (2) with respect to a total number of moles of the compound represented by the general formula) and the compound represented by the general formula (2) defined as 100: in the formula (1), a ring A represents a heterocycle represented by the formula (1a), the heterocycle being condensed with an adjacent ring at an arbitrary position, R's each represent a hydrogen atom, a C1 to C20 alkyl group, a C1 to C20 alkoxy group, a C6 to C30 aryl group, a C6 to C30 aryloxy group, a C7 to C36 arylalkyl group, a C7 to C36 arylalkyloxy group, a C3 to C30 heteroaryl group, a C3 to C30 heteroaryloxy group, a C4 to C36 heteroarylalkyl group, a C4 to C36 heteroarylalkyloxy group, or a C3 to C30 cycloalkyl group, and may be identical to or different from one another, Y1's each represent a divalent group and may be identical to or different from each other, and W1's each independently represent a radically polymerizable group or a cationically polymerizable group selected from the group consisting of a vinyl group, a substituted vinyl group substituted with an alkyl group having 1 to 6 carbon atoms, an epoxy group, and an oxetanyl group, and may be identical to or different from each other; and in the formula (2), Z represents a C6 to C30 aryl group, a C3 to C30 heteroaryl group, or a C12 to C60 diarylamino group, Y2 represents a divalent group, and W2 independently represents a radically polymerizable group or a cationically polymerizable group selected from the group consisting of a vinyl group, a substituted vinyl group substituted with an alkyl group having 1 to 6 carbon atoms, an epoxy group, and an oxetanyl group. |
