摘要： Color purity of a light emitting element is improved without an adverse effect such as reduction in voltage and luminance efficiency. The light emitting element has a light emitting laminated body including a light emitting layer between a pair of electrodes. A buffer layer is provided to be in contact with at least one of the electrodes. One of the electrodes is an electrode having high reflectance and the other is a translucent electrode. By employing a translucent electrode, light can be transmitted and reflected. An optical distance between the electrodes is adjusted in accordance with a thickness of the buffer layer, and accordingly, light can be resonated between the electrodes. The buffer layer is made of a composite material including an organic compound and a metal compound; therefore, voltage and luminance efficiency of the light emitting element is not affected even if a distance between the electrodes becomes long.
