LIGHT-EMITTING ELEMENT, LIGHT-EMITTING DEVICE, LIGHTING DEVICE AND ELECTRONIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting element having a peak of light emission near 620 nm because wave length of light being acknowledged as a good red color is a wave length near 620 nm.SOLUTION: A light-emitting element, a light-emitting device and an electronic apparatus are formed by employing an organometallic complex, shown by a general formula (G1), as guest material and employing a low molecular compound as host material.
