Abstract: An organic electroluminescence device includes, in order, a first electrode, a hole transport layer, an organic light-emitting layer, an electron transport layer, and a second electrode. The hole transport layer is configured by a coated film. The organic light-emitting layer is configured by a coated film. The organic light-emitting layer has a hole current that is larger than an electron current.

Abstract: An organic EL display panel that includes light-reflective electrodes, a red light-emitting layer, a green light-emitting layer, a first blue light-emitting layer, a charge generating layer, a second blue light-emitting layer, and a light-transmissive electrode. In a red sub-pixel region, a first optical length is from 20 nm to 50 nm, and a second optical length is from 210 nm to 230 nm. In a green sub-pixel region, the first optical length is from 20 nm to 50 nm, and the second optical length is from 240 nm to 295 nm. In a blue sub-pixel region, the first optical length is from 20 nm to 60 nm, and the second optical length is from 195 nm to 205 nm.

Abstract: An organic light-emitting device includes: an anode; a wiring that is disposed side-by-side with and spaced from the anode; a light-emitting layer that is disposed above the anode, and includes an organic light-emitting material; an intermediate layer that is disposed above the light-emitting layer and the wiring; an organic functional layer that is disposed above the intermediate layer, and has an electron injection property or an electron transport property; a cathode that is disposed above the organic functional layer. The intermediate layer includes: a fluoride of a first metal, the first metal being an alkali metal or an alkaline-earth metal; and a second metal that has a property of cleaving a bond between the first metal and fluorine in the fluoride.
