1. A display device comprising:
a pixel component including scan lines extending in a first direction, data lines extending in a second direction, and pixels electrically connected to the scan lines and the data lines, and defining pixel columns and pixel rows;
a data driver disposed on a side of the pixel component and electrically connected to the data lines; and
a scan driver disposed on the side of the pixel component and electrically connected to the scan lines, wherein
the pixel component comprises:
sub-scan lines extending from the scan driver in the second direction; and
dummy lines extending in the second direction,
each of the scan lines is electrically connected to the sub-scan lines in a ratio of 1:n (where n is an integer greater than 1) by contacts,
the contacts are divided into contact groups, the contacts in each of the contact groups arranged colinearly in a diagonal direction with respect to the first direction,
the pixel component is divided into pixel blocks corresponding to respective contact groups,
each of the pixel blocks includes a first area and a second area divided by a corresponding one of the contact groups,
in a pixel column, the first area is closer to the scan driver than the second area,
the pixel component further includes, in the second area, supplementary power lines spaced apart from a corresponding one of the sub-scan lines in the second direction,
the second area includes residual areas having an identical arrangement structure of the sub-scan lines, the dummy lines, the data lines, and the supplementary power lines, and
the residual areas are arranged in the first direction.
