Abstract:
1. An organic electroluminescent display device, comprising: a substrate; a first electrode formed on the substrate; a reforming layer formed directly on the first electrode, the reforming layer being formed of a general soluble polymer or a fully fluorine-substituted or partially fluorine substituted fluorine-based polymer which includes at least one or more functional group selected from a group consisting of a ketone group, a carboxyl group, an ester group, an ether group, an amide group, an amine group, a silane group, a sulfone group and an aromatic group in its main-chain or side-chain; an organic emission layer formed over an upper surface of the reforming layer; and a second electrode formed over the organic emission layer, wherein the general soluble polymer is one kind of polymer selected from a group consisting of poly(acrylics) or poly(methacrylics) and its derivatives, poly(acrylates) or poly(methacrylates) and its derivatives, poly(acrylamides) or poly(methacrylamides) and its derivatives, unsubstituted or substituted polydienes, poly(vinyl ethers) and its derivatives, poly(acetals) and its derivatives, poly(vinyl ketones) and its derivatives, poly(vinyl nitriles) and its derivatives, poly(vinyl esters) and its derivatives, poly(styrenes) and its derivatives, aliphatic, aromatic and aliphatic-aromatic poly(oxides), poly(carbonates) derivative, aliphatic, aromatic and aliphatic-aromatic poly(esters), poly(urethanes) derivative, pol(aryl sulfonates) derivative, poly(siloxanes) derivative, aliphatic, aromatic and aliphatic-aromatic pol(amides) and its derivatives.
