Organic electroluminescent element and light-emitting device or display device incorporated therewith

An organic electroluminescent element in which organic layers having an emitting layer for emitting red light are formed between the anode and the cathode, characterized in that the emitting layer is formed from a mixture comprised of at least one species of the styryl compounds represented by the general formula given below and an electron transporting material selected from the group consisting of 8-hydroxyquinoline aluminum (Alq3), anthracene, naphthalene, phenanthrene, pyrene, chrysene, perylene, butadiene, coumarin, acridine, and stilbene, and derivatives thereof, and further comprising at least one member from the group consisting of DCM, porphins, phthalocyanines, perylene compounds, Nile red, or squarilium compounds,
