An organic electroluminescence element is composed of a plurality of first electrodes that are disposed on a substrate in matrix, a second electrode that is disposed with being confronted with each of the plurality of first electrodes and a emissive layer formed between each of the plurality of first electrodes and the second electrode on each of the plurality of first electrodes, wherein the emissive layer is composed of a blue (B) emissive layer, a green (G) emissive layer and a red (R) emissive layer as a set of pixels, the organic electroluminescence element is further characterized in that the B emissive layer contains a B emissive material, the G emissive layer contains B and G emissive materials, and the R emissive layer contains B and G and R emissive materials. Accordingly, the organic electroluminescence element is small in size and high in definition, performance and productivity.

Organic electroluminescence element and manufacturing method thereof

A magnetic recording medium has a substrate and a magnetic layer formed on the substrate. The magnetic layer includes magnetic powder and a binder for binding the magnetic powder on the substrate. The binder includes at least a resin component containing at least an aminoquinone structure selected from an aminoquinone structure group shown with formulas (1-1a), (1-1b), (1-3a) and (1-3b) as a constitutional unit and at least a polar group selected from a group shown with a formula (1-2) in a composition of the resin component. Thus, the magnetic recording medium has excellent corrosion resistance of the magnetic powder and excellent conservation and running durability.
