<p>A light emitting element and a light emitting device are provided to lower power consumption and improve color purity without appearance of an adverse effect such as reduction in voltage and luminance efficiency. A light emitting device includes a light emitting element having a pair of electrodes, and a layer containing an organic compound interposed between the pair of electrodes. The layer containing an organic compound has a light emitting layer containing a light emitting substance, and buffer layers(401-1,401-2) having a composite material containing an organic compound of a hole transporting property and a metal compound. One of the pair of electrodes is an electrode having high reflectance and the other is a translucent electrode. An optical distance between the pair of electrodes is an integral multiple of half of a maximum wavelength of light extracted from the light emitting element.</p> |
