Abstract:
An organic EL device includes a light-transmitting substrate, a light-transmitting first electrode layer arranged on the substrate, three or more light-emitting units layered and arranged on the first electrode layer, each of the light-emitting units including a central organic emission layer, a hole transfer layer and an electron transfer layer, a plurality of charge generation layers, each of the charge generation layers being interposed and arranged between two corresponding adjacent ones of the light-emitting units, and a second electrode layer arranged on the light-emitting unit positioned highest in a layering direction among the light-emitting units. The total thickness of the layers interposed between the first electrode layer and the second electrode layer being 360 nm or less.
