An electro luminescence display device is provided, including a plurality of pixels arranged in a two dimensional direction, each pixel having a plurality of different kinds of organic electro luminescence elements differing from each other in the color of the emitted light, and each of the organic electro luminescence elements having an anode, a cathode, and a polymer light-emitting layer located between the anode and the cathode, wherein the polymer light-emitting layer emitting light of at least one color includes a nonionic surfactant having a fluorine-substituted alkyl group containing, e.g., an alkyl silyl group.

Organic electro luminescence display device

The method of isolating organic compound-degradable microorganisms included in this invention is characteristic in that microorganisms in the organic compound contaminated sample, for example an environment sample, are cultured in a carbon-free medium, at the same time, are contacted with organic compounds mainly as the gas phase, and selected by the tolerance to the organic compounds as the index. Also, the method for biodegradation of organic compounds is characteristic in that the microorganism thus isolated, for example, Komagatella brevis, is contacted with contaminated soil or contaminated underground water, and without the addition of additives or inducing substances for organic compounds decomposing enzymes, may effectively biodegrade the organic compounds in the environment.
