Abstract: In the contact structure according to an exemplary aspect of the present disclosure and a display device including the same, the pixel may be designed regardless of the size of the contact hole by designing a size (or an area) of the contact hole to be larger than the contact area and applying different structures depending on the characteristics of the lower layer. Therefore, the size of the contact hole is increased so that the halftone mask may be easily applied and the number of masks may be advantageously reduced. Further, a degree of freedom of metal in the pixel design is increased so that the pixel may be designed in a high resolution model and the aperture ratio is increased without having the electrode margin. The contact structure comprises: a lower layer; at least a first insulating layer on the lower layer, the first insulating layer having a predetermined contact hole to expose a part of the lower layer; and an upper layer on the first insulating layer to be in contact with the lower layer through the contact hole, wherein the contact hole has a relatively larger area than a contact area where the upper layer and the lower layer are in contact with each other.

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.
