Abstract
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.
