Abstract: An organic EL element includes: an anode; a light-emitting layer that is disposed above the anode; a first interlayer that is disposed on the light-emitting layer; a second interlayer that is disposed on the first interlayer; a functional layer that is disposed on the second interlayer; and a cathode that is disposed above the functional layer. The first interlayer includes a fluorine compound including a first metal that is an alkali metal or an alkaline-earth metal. The second interlayer includes a second metal that has a property of cleaving a bond between the first metal and fluorine in the fluorine compound. The functional layer has at least one of an electron transport property and an electron injection property. A thickness D1 of the first interlayer and a thickness D2 of the second interlayer satisfy 3%≦D2/D1≦25%.
