Abstract: A display panel including a substrate, anodes disposed on or above the substrate, light-emitting layers disposed on or above the anodes, a first intermediate layer disposed on or above the light-emitting layers, a second intermediate layer disposed on the first intermediate layer, and a cathode disposed on or above the second intermediate layer. The first intermediate layer includes a fluoride of a first metal or a complex of the first metal. The second intermediate layer includes a second metal. The anodes are light-transmissive and the cathode is light-reflective, or the anodes are light-reflective and the cathode is light-transmissive. The first metal is selected from a group consisting of alkali metals and alkaline earth metals. The second metal is selected from rare earth metals.

Abstract: An organic electroluminescence (EL) element including an anode, a cathode opposing the anode, a light-emitting layer between the anode and the cathode, a hole transport layer in contact with the light-emitting layer, between the light-emitting layer and the anode, and an electron transport layer in contact with the light-emitting layer, between the light-emitting layer and the cathode. A difference between a lowest unoccupied molecular orbital (LUMO) level of an organic material included in the light-emitting layer and a LUMO level of an organic material included in the electron transport layer is greater than a difference between a highest occupied molecular orbital (HOMO) level of an organic material included in the hole transport layer and a HOMO level of the organic material included in the light-emitting layer.
