Abstract
The present disclosure discloses an organic light emitting display device having a substrate including an active area configured to display an image and an inactive area configured to surround the active area; a power supply line in the inactive area; a first planarization layer on a layer where the power supply line is disposed on; a first metal layer on the first planarization layer and in contact with the power supply line; a second planarization layer configured to planarize an upper portion of the first metal layer; and a second metal layer, on the second planarization layer, and in contact with the first metal layer and a cathode of an organic light emitting diode.

An organic light emitting display device comprising:
- an active area and an inactive area on a substrate, the active area configured to display an image and an inactive area surrounding the active area;
- a power supply line in the inactive area;
- a first planarization layer on a layer where the power supply line is disposed;
- a first metal layer on the first planarization layer and in contact with the power supply line;
- a second planarization layer planarizing an upper portion of the first metal layer;
- and
- a second metal layer on the second planarization layer and in contact with the first metal layer and a cathode of the organic light emitting diode.
A display device comprising:
- an active area and an inactive on a substrate, the active area including a matrix of pixels and the inactive area adjacent to the active area;
- and
- a dual-layer planarization structure, having a first planarization layer and a second planarization layer thereon, over the active area and extending into the inactive area,
- wherein the inactive area has a first region, adjacent to the active area, in which a Gate-In-Panel (GIP) structure is located, the GIP structure configured to transfer gate signals to the pixels;
- the inactive area has a second region, adjacent to the first region, in which a power supply line is located, the power supply line configured to transfer voltage to the pixels, and
- the first and second regions have an overlapping section that provides a space for a narrow bezel.
