摘要： 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.

摘要： In an organic electroluminescent element provided with a blue light-emitting layer and an orange light-emitting layer as a light-emitting layer between a hole injection electrode and an electron injection electrode, the blue light-emitting layer contains a host material, a light-emitting dopant and an assist dopant supplementing the carrier transfer of the host material. When the host material is an electron transfer material, an assist dopant has a smaller absolute value of highest occupied molecular orbital (HOMO) energy level than that of the host material and has a higher hole mobility than that of the host material.
