    摘要： A hole injection electrode of a transparent conductive film such as indium-zinc-oxide is formed on a substrate, and a hole injection layer, a hole transport layer, a light emitting layer, and an electron transport layer are formed in this order on the hole injection electrode. Then, an electron injection electrode made of a material such as aluminum is formed on the electron transport layer. The hole injection layer is made for example of fluorocarbon (CFx). The thickness of the hole injection layer is preferably in the range from 30 Å to 90 Å.

    摘要： A method of manufacturing an organic EL display in which organic EL devices are prevented from being promoted in degradation by interfaces that occur between the hole transporting layer and the luminescent layer and between the luminescent layer and the electron transporting layer during the formation of the organic EL devices. The material of the luminescent layer is evaporated from a first evaporation source. At that time, the first evaporation source is moved from one end of a glass substrate to the other. Consequently, the luminescent layer is formed evenly on the glass substrate. After the formation of the luminescent layer is completed, the material of the electron transporting layer is evaporated from a second evaporation source. The second evaporation source is moved as if the first evaporation source is, whereby the electron transporting layer is formed evenly.

    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.

    摘要： A light-emitting device including a plurality of emission layers, which has improved luminous efficiency and improved reliability (or device lifetime), is provided. The light-emitting device includes a first emission layer formed on a substrate, and a second emission layer formed on the first emission layer to provide a laminated structure, for emitting light having a different wavelength from that of light emitted by the first emission layer. At least one of the first emission layer and the second emission layer includes a host material, a luminescent first dopant material and a non-luminescent second dopant material.
