1. A display panel comprising:
a first sub-display panel;
a second sub-display panel adjacent to the first sub-display panel in a first direction; and
a connection member electrically connecting the first sub-display panel to the second sub-display panel, wherein
the first sub-display panel includes:
a first pixel disposed in a first pixel area among the plurality of the pixel areas;
a second pixel between and adjacent to the first pixel and the second sub-display panel, and disposed in a second pixel area among the plurality of the pixel areas;
a first power voltage line for transferring a power voltage to the first pixel, extending in a second direction perpendicular to the first direction, and disposed in the first pixel area; and
a first gate line electrically connected to the first pixel and the second pixel, the first gate line extending in the first direction,
the second pixel receives the power voltage from the first power voltage line,
the second sub-display panel includes a third pixel adjacent to the first sub-display panel, and
the third pixel is electrically connected to the first gate line,
wherein the third pixel is disposed only on one first side of the connection member, while the first and second pixels are disposed on only a second side of the connection member, which is opposite to the first side,
wherein the first sub-display panel further includes a first connection pad disposed between and adjacent to the second pixel and the second sub-display panel,
wherein the second sub-display panel further includes a second connection pad disposed between and adjacent to the third pixel and the first-sub display panel,
wherein the connection member includes a plurality of conductive balls overlapping the first connection pad and the second connection pad,
wherein the first connection pad is electrically connected to the first gate line, and
wherein the conductive balls electrically connect the first connection pad and the second connection pad.
