Abstract
A layout structure of electrode lead wires for organic light-emitting diode (OLED) display is provided for saving materials, simplifying fabrication process, and reducing power consumption so as to lower down the required driving voltage. The display comprises a plurality of cathode and anode electrodes and a plurality of electrode lead wires connected to the cathode electrodes and the anode electrodes respectively. The cathode and the anode lead wires made of a multi-layer metallic material having high conductivity and low impedance are laid on the same side of the transparent substrate.
