Abstract
A self-luminous element includes: a pixel electrode; a light-emitting layer that is disposed above the pixel electrode and includes a light-emitting material; a first functional layer that is disposed on the light-emitting layer and includes a metal fluoride; a second functional layer that is disposed on the first functional layer and includes a first organic material having at least one of electron transport properties and electron injection properties; and a counter electrode that is disposed above the second functional layer. The second functional layer does not include at least one metallic element selected from the group consisting of alkali metals, alkaline earth metals, and rare earth metals that reduce the metal fluoride.
