摘要:
A light-emitting layer emits light having an emission spectrum having a primary peak in the range of wavelengths of 430 to 480 nm. The light-emitting layer contains a host compound and a dopant compound. The dopant compound has an electron affinity of 2.93 eV or more higher that is than the host compound. The dopant compound in the lowest excited triplet state has an energy of 1.95 eV or less that is lower than the host compound in the lowest excited triplet state. The dopant compound has a smaller band gap than the host compound. The dopant compound is a hydrocarbon compound.

摘要:
The present invention provides a stable new condensed polycyclic compound which is not likely to form a molecular association. In addition, the present invention also provides an organic light-emitting element having a high light-emitting efficiency and a low drive voltage. In the condensed polycyclic compound in Claim 1 represented by the general formula [1], R1, R2 and R5 are each independently selected from a hydrogen atom, an alkyl group having 1 to 4 carbon atoms, an aryl group, and a heterocyclic group. R3 and R4 each represent an alkyl group having 1 to 4 carbon atoms. The aryl group and the heterocyclic group each may have at least one of an alkyl group, an aralkyl group, an aryl group, a heterocyclic group, an amino group, and an alkoxy group as a substituent.
