Abstract
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.
