Abstract
An organic light-emitting display device includes a thin film transistor including an active layer, a gate electrode, source/drain electrodes, a first insulating layer between the active layer and the gate electrode, and a second insulating layer over the gate electrode; a pixel electrode on the first insulating layer and the second insulating layer and connected to the source or drain electrode; a first wire on the first insulating layer, of the same material as the gate electrode; a second wire on the second insulating layer to at least partially overlap the first wire and including a lower wiring layer of the same material as the pixel electrode and an upper wiring layer on the lower wiring layer, of the same material as the source/drain electrodes; and third insulating layers between the second insulating layer and the pixel electrode and between the second insulating layer and the second wire.
