摘要： A top-emission type light emitting display device and a corresponding manufacturing method are described. A device substrate has display area and non-display areas. In the display area are formed: a thin film transistor including an active layer, a gate electrode, a source electrode, and a drain electrode; and an organic light emitting element including an anode, an organic light emitting layer, and a cathode. In the non-display area a second voltage supply wire is formed on, and overlaps with, a first voltage supply wire. An anti-burning layer is disposed between the first voltage and the second voltage supply wires.
