16. A display device comprising:
a display area including a plurality of pixels and having a scan area and a power area disposed on a side of the scan area; and
a non-display area surrounding the display area and having a pad part, wherein
the scan area includes:
a first voltage line extending in a first direction on a side of the pixel to supply a high potential voltage; and
a plurality of vertical gate lines disposed on a side of the first voltage line to supply a gate signal, and
the power area includes:
a first voltage line extending in a first direction on a side of the pixel to supply a high potential voltage; and
a plurality of power lines disposed on a side of the first voltage line to supply a power voltage, and
the pad part includes:
a first pad part including a plurality of line pad parts electrically connected one-to-one to the first voltage line and the plurality of vertical gate lines; and
a second pad part including one or more line pad parts electrically connected one-to-one to the first voltage line, and a power pad part electrically connected one-to-many to the plurality of power lines, and wherein
the power pad part of the second pad part is adjacent to the one or more line pad parts of the second pad part,
