Abstract
An organic light-emitting device includes: an organic light-emitting device that includes: a cathode; an anode facing the cathode; a functional layer located between the cathode and the anode, the functional layer including a light-emitting layer; and an electron-injection layer located between the cathode and the functional layer, the electron-injection layer at least partially composed of a metallic compound containing a metal element, wherein the electron-injection layer includes crystal grains in which the metallic compound is crystallized and the metal element has a d10 electron configuration in the outermost shell, and at least one of the crystal grains is in contact with both the cathode and the functional layer.
