Active Material Comprising Organic Conducting Material, E.g., Conducting Polymer (epo) Patents (Class 257/E21.007)
  • Patent number: 7163831
    Abstract: The present invention provides an light-emitting element in which an organic compound layer containing a carbonate, for example Cs2CO3 and Li2CO3, as a dopant is in substantially electrical contact with a cathode by providing an organic compound layer having a dopant easy in handling so as to bring the organic compound layer into contact with the cathode. The light-emitting element includes a pair of electrodes sandwiching the organic compound layer, which is a co-evaporation layer of an organic compound and the carbonate.

  • Patent number: 7144752
    Abstract: A method of manufacturing an organic electroluminescent display device, an organic electroluminescent display device, and a display device equipped with an organic electroluminescent display device are provided that enable a microlens to be formed without affecting an organic luminescent layer during the manufacturing process and to easily manufacture an organic electroluminescent display device with increased light output efficiency. According to the method, a lens pattern corresponding to a microlens that refracts the light from an organic luminescent layer is formed by performing photolithography treatment on a first transparent resin film formed on a substrate, and the microlens is formed by performing reflow treatment on the lens pattern.
