Abstract: A display panel may include a substrate, pixels, dummy pixels, and voltage lines. The substrate may include a first transmission region for light transmission and/or sound transmission, a non-display area surrounding the first transmission region, and a display area surrounding the non-display area. The pixels may be arranged on the display area and may emit light. The dummy pixels may be arranged on the non-display area, may include a first dummy pixel, and may emit no light. The voltage lines may transmit voltages to the pixels and the dummy pixels. The voltage lines may include a first voltage line and a second voltage line. The first voltage line may be spaced from the second voltage line, may be aligned with the second voltage line, and may overlap the first dummy pixel. The first transmission region may be positioned between the first voltage line and the second voltage line.
