Organic light emitting display apparatus

An organic light emitting display apparatus comprising:

• a base layer comprising a display area and a non-display area adjacent to the display area;
• a circuit element layer comprising a first transistor in the display area including a first semiconductor pattern, a first transistor electrode electrically connected to the first semiconductor pattern, and a second transistor electrode electrically connected to the first semiconductor pattern, a first control electrode overlapping the first semiconductor pattern, a lower insulating layer covering the first control electrode, an upper insulating layer disposed on the lower insulating layer, a power supply line to receive a common voltage, an auxiliary power supply pattern electrically connected to the power supply line, a voltage line to receive a source voltage greater than the common voltage and electrically connected to the first transistor electrode, and an auxiliary voltage pattern electrically connected to the voltage line;
• and
• a display element layer comprising a first electrode on the circuit element layer and electrically connected to the second transistor electrode, a light emitting layer on the first electrode, and a second electrode on the light emitting layer and electrically connected to the power supply line;
• wherein the power supply line and the voltage line are located between the lower insulating layer and the upper insulating layer,
• wherein the auxiliary power supply pattern and the auxiliary voltage pattern are disposed on the upper insulating layer and are in contact with the upper insulating layer.
