Patent ID: 7795808

Claim:
An organic EL display device which forms each of a plurality of organic EL layers between a respective upper electrode which constitutes an anode and a respective lower electrode which constitutes a cathode, and makes use of emission of light generated by supplying an electric current to the organic EL layers, the organic EL display device comprising: a plurality of TFTs formed on a substrate, each TFT having a semiconductor layer, a gate insulation film and a gate electrode; an interlayer insulation film formed on the substrate to cover the plurality of TFTs; a plurality of SD lines connected with the semiconductor layers of the TFTs and extending over the interlayer insulation film to thereby form the lower electrodes of the organic EL layers, each SD line being formed of a plurality of SD layers including an uppermost layer and a metal layer, the uppermost layer of each SD line being formed of a transparent conducive film and not forming any of the lower electrodes of the organic EL layers, the metal layer of each SD line being made of metal or metal alloy which reflects light; and a plurality of terminal portions connected with the TFTs and the upper electrodes and formed on the substrate, the upper electrodes being formed of a transparent electrode, the terminal portions being formed on a same layer as the SD lines.
