Abstract: An organic light emitting diode display is described which includes a substrate having a display area and a non-display area; a metal layer disposed on the non-display area of the substrate, an insulating layer, a voltage line disposed on the gate insulating layer and receiving a driving voltage, a second voltage line disposed on the gate insulating layer and receiving a low driving voltage, an organic insulating layer, and a cathode electrode disposed on the organic insulating layer. The second voltage line and the cathode electrode are electrically connected to each other through an opening formed in the organic insulating layer, and the first voltage line or the second voltage line is electrically connected to the metal layer through an opening formed in the gate insulating layer.

Abstract: An organic light emitting display device includes a thin film transistor on a substrate including a display area having an inner light-emitting area and an outer light-emitting area and a peripheral area, a first conductive member connected to the thin film transistor, a first via insulation layer covering the first conductive member, a second conductive member on the first via insulation layer to overlap the outer light-emitting area and a part of the peripheral area, a second via insulation layer covering the second conductive member, a first electrode on the second via insulation layer to overlap the display area and a part of the peripheral area, an organic light emitting layer on the first electrode, and a second electrode on the organic light emitting layer. The second via insulation layer and the first electrode have a step structure between the inner and outer light-emitting areas.

Abstract: A display device includes: a substrate including a display area, and a non-display area defined around the display area, a driver disposed in the non-display area on the substrate, first crack detection lines disposed in the non-display area on the substrate, where a part of each of the first crack detection lines adjacent to an end of the driver extends in parallel with an edge of the substrate, a second crack detection line disposed in the non-display area on the substrate, electrically connected to the first crack detection lines, and positioned between the first crack detection lines and the driver, and a common voltage line disposed in the non-display area on the substrate. A concave portion overlapping at least a part of the second crack detection line in a plan view is defined at an edge portion of the common voltage line facing the first crack detection lines.

Abstract: A display apparatus includes a display area in which a plurality of pixels are disposed to display an image and a peripheral area which is a non-display area. The display apparatus includes a first power line which is disposed in the peripheral area and provides a first voltage to the plurality of pixels, and a second power line which is disposed in the peripheral area and provides a second voltage different from the first voltage to the plurality of pixels. At least a portion of the first power line overlaps the second power line in the peripheral area.
