Patent ID: 7723735

Claim:
A display device having: a plurality of organic electroluminescence devices arranged on a substrate, each of the organic electroluminescence devices including a lower electrode, an organic layer containing at least one light emitting layer, and an upper electrode in this order, wherein at least three of said organic electroluminescence devices, each of which emits a different color, have a common first light emitting layer, at least one of said at least three organic electroluminescence devices has a second light emitting layer which is stacked above said first light emitting layer, the first light emitting layer emits light with a wavelength that is equal to or shorter than that of blue light, the at least three of said organic electroluminescence devices have in common, distinctly from the first light emitting layer, a hole injecting layer, a hole transporting layer, an electron injecting layer and an electron transporting layer, the hole injecting and transport layers are located below the first light emitting layer and the second light emitting layer, and the electron injecting and transport layers are located above the first light emitting layer and the second light emitting layer.
