Abstract: A display panel is disclosed that includes a substrate, a first initialization voltage line, and a second initialization voltage line. The substrate includes a display area and a peripheral area. The first initialization voltage line is arranged in the display area and includes a first vertical voltage line and a first horizontal voltage line. The second initialization voltage line includes a second vertical voltage line and a second horizontal voltage line overlapping the first horizontal voltage line in a plan view. Each of the plurality of pixels includes a first sub-pixel configured to emit light of a first color, and a second sub-pixel configured to emit light of a second color. The first initialization voltage line is configured to transmit a first initialization voltage to one electrode of a light-emitting diode of the first sub-pixel. The second initialization voltage line is configured to transmit a second initialization voltage to one electrode of a light-emitting diode of the second sub-pixel.
