摘要:
A display device and a method for fabricating the display device. A display device according to the present invention is fabricated from an electrode layer that includes a plurality of electrodes on a substrate. The electrode layer is immersed in a solution of a first precursor polymer in a first solvent. The first precursor polymer includes a plurality of electrochemical polymerizable monomers. Each monomer has first and second polymer-forming active sites that can be joined by electrochemical polymerization and third and fourth polymer-forming active sites that can be joined chemically in solution. The first precursor polymer is soluble in the first solvent whereas a first polymer formed by electrochemical polymerization of the first and second polymer-forming active sites is insoluble in the first solvent. A layer of the first polymer is deposited on the a first one of the electrodes by connecting that electrode to an electric circuit while leaving the others of the electrodes disconnected from the circuit. The electrode is then immersed in a solution of said first precursor polymer. The circuit applies a potential to the electrode sufficient to cause the first and second polymer active sites to polymerize by electrochemical polymerization thereby depositing a first polymer layer includes the first polymer precursor on the first one of the electrodes. A second electrode layer is then deposited over the first polymer layer. In multi-color displays, the different polymer layers corresponding to the various colors are deposited on different ones of the electrodes by sequentially depositing each polymer layer in a similar manner.
