1. A display device comprising:
a plurality of pixels substantially in a matrix form including a plurality of pixel columns arranged along a first direction, and a plurality of pixel rows arranged along a second direction intersecting the first direction;
a plurality of data lines connected to the pixel columns, respectively; and
a power line to supply a driving power voltage to at least some of the plurality of pixels,
wherein each of the data lines comprises:
a first sub-data line disposed at a side of a corresponding pixel column; and
a second sub-data line disposed at an opposite side of the corresponding pixel column, and
wherein the power line comprises:
a first power supply line disposed on a first layer extending in a pixel column direction; and
a second power supply line disposed on a second layer different from the first layer and extending in the pixel column direction,
wherein the second power supply line is electrically connected to the first power supply line, and
wherein the second power supply line extending along the pixel column direction overlaps a substantial length defining the first power supply line extending along the pixel column direction.
