| Abstract | An organic light-emitting display device includes a plurality of pixels, each of which includes an organic light-emitting device including a pixel electrode, an organic emission layer, and an opposing electrode; a pixel defining layer covering an edge of the pixel electrode and being configured to define a light-emission region by having an opening which exposes a portion of the pixel electrode; and a reference line overlapping the pixel electrode with an insulating layer between the reference line and the pixel electrode and extending in a first direction. The reference line overlaps with a center point of the opening, and the opening is shifted to one side of the pixel electrode in a second direction perpendicular to the first direction. |

| Claim | An organic light-emitting display device comprising: a plurality of pixels, at least one of the plurality of pixels comprising an organic light-emitting device on a substrate, the organic light-emitting device comprising a pixel electrode, an organic emission layer, and an opposing electrode; a pixel defining layer covering the pixel electrode defining a light-emission region by having an opening which exposes a portion of the pixel electrode; at least one of a driving voltage line, a data line, and a contact line overlapping the pixel electrode; and an insulating layer over the at least one of a driving voltage line, the data line, and the contact line, wherein the insulating layer is disposed below the pixel electrode, wherein: the insulating layer has a first irregular portion in a direction perpendicular to an upper surface of the substrate; the pixel electrode has a second irregular portion in a direction perpendicular to an upper surface of the substrate; and at least a portion of the first irregular portion and the second irregular portion located in the opening of the pixel defining layer in a plan view. The organic light-emitting display device of claim 1, wherein the driving voltage line overlaps with the first irregular portion. The organic light-emitting display device of claim 1, wherein: the opening has a first vertex and a second vertex facing each other; and the driving voltage line passes through the first vertex and the second vertex in a plan view. The organic light-emitting display device of claim 1, wherein one of the driving line, the data line, and the contact line passes through the center point of the opening as a reference line, and the other ones of the driving line, the data line, and the contact line are symmetrically disposed with respect to the reference line in a plan view. The organic light-emitting display device of claim 4, wherein the reference line extends in a first direction in a plan view, and the opening is shifted to one side of the pixel electrode in a second direction, which is perpendicular to the first direction in the plan view. The organic light-emitting display device of claim 5, further comprising a via hole overlapping the pixel electrode, wherein the plurality of pixels comprise a first pixel and a second pixel, and the via hole of the first pixel and the via hole of the second pixel are arranged on a virtual line extending the second direction. The organic light-emitting display device of claim 1, the driving voltage line, the data line, and the contact line are disposed on a same layer. The organic light-emitting display device of claim 1, further comprising a driving thin film transistor arranged on a substrate and comprising a driving gate electrode, and at least a portion of the pixel electrode overlaps with the driving gate electrode. The organic light-emitting display device of claim 8, further comprising a storage capacitor having an upper electrode and a lower electrode, wherein the lower electrode is integrally provided with the driving gate electrode. The organic light-emitting display device of claim 9, wherein: the driving thin film transistor comprises a driving semiconductor layer arranged under the driving gate electrode and is insulated from the driving gate electrode by a first gate insulating layer; and a second gate insulating layer is arranged between the lower electrode and the upper electrode. |
