Abstract
The present invention provides an organic electroluminescent element which is superior in luminance, reliability, and thermal stability and is capable of selectively emitting light with comparative long wavelengths such as red and good color purity and a light-emitting device or display device incorporated therewith. The organic electroluminescent element consists of a glass substrate (), an anode (), a hole transporting layer (), an emitting layer (), an electron transporting layer (), and a cathode (), which are sequentially laminated on top of the other. The emitting layer () is formed from a mixture composed of at least one species of the styryl compound represented by the general formula [I] below and a material with charge transporting capability.Y—CH═CH—X   General formula [I](where X denotes an aryl group (such as phenyl group) which has a substituent group (such as cyano group and methyl group), and Y denotes a group having a skeleton of aminophenyl group or the like.)
