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.
