1. A display panel including a display area and a peripheral area outside the display area, the display panel comprising:
a first initialization voltage line extending in a first direction in the display area and configured to transmit a first initialization voltage;
a second initialization voltage line extending in the first direction in the display area and configured to transmit a second initialization voltage;
a first transistor in a first pixel area of the display area and including a first semiconductor layer connected to the first initialization voltage line, and a first gate electrode;
a second transistor in a second pixel area adjacent to the first pixel area, the second transistor including a second semiconductor layer connected to the second initialization voltage line, and a second gate electrode; and
a first connection electrode in the second pixel area,
wherein the first initialization voltage line and the second initialization voltage line are on different layers from each other, and the first initialization voltage line and the first connection electrode are on a same layer,
wherein the first initialization voltage line extends in a zigzag shape and directly contacts the first semiconductor layer through a contact hole, and
the second initialization voltage line extends in a straight line shape and is connected to the second semiconductor layer by using the first connection electrode, and
wherein the first transistor transmits the first initialization voltage to a pixel electrode of a first light-emitting diode configured to emit light of a first color, and the second transistor transmits the second initialization voltage to a pixel electrode of a second light-emitting diode configured to emit light of a second color.
