Abstract
A display device is disclosed. The display device according to an exemplary embodiment of the present disclosure includes: a substrate including an active area and a non-active area; an active layer, a thin film transistor including a gate electrode, a source electrode, and a drain electrode disposed on the substrate; and an organic light emitting diode including an anode which is electrically connected to the thin film transistor, in which the gate electrode, the source electrode, and the drain electrode are formed of a first conductive layer and a second conductive layer on the first conductive layer and the anode is formed of the same material as the first conductive layer. Therefore, the anode and the first conductive layer of the drain electrode are integrally connected so that a separate contact hole for electrically connecting the anode and the drain electrode is not necessary and the structure may be simplified.
