An organic EL display in which organic EL devices are prevented from being
degraded because of interfaces occurring between the luminescent layers
and the electron transporting layers. In each of the organic EL devices,
a red luminescent layer, a green luminescent layer, and a blue
luminescent layer are formed on a hole transporting layer. An electron
transporting layer is formed on the blue luminescent layer alone. The red
luminescent layer and the green luminescent layer have the same thickness
as the sum of the thicknesses of the electron transporting layer and the
blue luminescent layer.
