    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.
