Abstract
A light emitting element according to an embodiment includes a first electrode, a second electrode disposed on the first electrode, and an emission layer disposed between the first electrode and the second electrode. The emission layer includes a first compound, and at least one of a second compound, a third compound, and a fourth compound. The first compound is represented by Formula 1, the second compound is represented by Formula HT-1, the third compound is represented by Formula ET-1, and the fourth compound is represented by Formula M-b. Accordingly, the light emitting element has decreased driving voltage and improved efficiency.
