    Abstract: A display device includes a substrate including a display area and a peripheral area disposed outside of the display area. The display area includes a plurality of pixels. The display device further includes an inorganic insulating layer disposed in the display area. The inorganic insulating layer includes a groove disposed in a region between the plurality of pixels. The display device further includes an organic material layer filling the groove, a first connection wiring, and a second connection wiring. The first connection wiring is disposed on the organic material layer, overlaps the plurality of pixels, and extends in a second direction. The second connection wiring is insulated from the first connection wiring, and extends in a first direction that crosses the second direction.

    Abstract: An organic light emitting display apparatus includes a base layer, a circuit element layer, a display element layer, an encapsulation layer, and a sealing member. The circuit element layer includes a power supply line on the base layer and an auxiliary power supply pattern on and connected to the power supply line. The display element layer includes a first electrode, a light emitting layer, and a second electrode, which are sequentially stacked on the circuit element layer. The second electrode is electrically connected to the auxiliary power supply pattern. The sealing member is between the circuit element layer and the encapsulation layer to overlap with the auxiliary power supply pattern when viewed in a plan view.
