Abstract: An organic light emitting diode display includes a lower substrate, a sub-pixel structure, an upper substrate, a sealant, and a first power supply wire. The lower substrate has a display area, a peripheral area, and a pad area. The sub-pixel structure is disposed in the display area on the lower substrate. The upper substrate is disposed on the sub-pixel structure. The sealant is disposed in the peripheral area between the lower substrate and the upper substrate. The first power supply wire is disposed between the lower substrate and the sealant, and overlaps the lower substrate and the sealant. The first power supply wire includes a first protrusion protruding in a first direction that is a direction from the pad area to the display area in the first peripheral area.

Abstract: A display device includes a substrate including a display area, a pad area where pads are positioned, and a bending area positioned between the display area and the pad area in a plan view; a test line part on the substrate in the pad area adjacent to the bending area, and to which a first constant voltage is applied; a (1-1)-th power line on the substrate in the pad area, adjacent to the test line part in a second direction crossing the first direction, and to which the first constant voltage is applied; a (2-1)-th power line between the (1-1)-th power line and the pads in the plan view, and to which a second constant voltage different from the first constant voltage is applied; and a (1-2)-th power line between the (2-1)-th power line and pads in the plan view, and to which the first constant voltage is applied.

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.
