Abstract
An organic EL element (10) includes a first electrode (110), an organic layer (120), and a second electrode (130). The organic layer (120) is located between the first electrode (110) and the second electrode (130). The second electrode (130) includes Ga in the vicinity of an interface with the organic layer (120). The second electrode (130) includes, for example, a Ga-containing layer (132) and a conductive layer (134). In the Ga-containing layer (132), an element having a highest content rate is Ga. The Ga-containing layer (132) is, for example, a thin Ga layer.
