1. A display device, comprising:
a substrate including a display area and a non-display area;
a pixel unit provided in the display area, and including a first pixel column including a plurality of pixels and a second pixel column including a plurality of pixels, the second pixel column displays a different color from a color of the first pixel column; and
data lines respectively connected to the first pixel column and the second pixel column, and respectively applies data signals to the first pixel column and the second pixel column,
wherein the data line connected to the first pixel column includes sub lines and the data line connected to the second pixel column includes sub lines,
in the non-display area, the sub lines connected to the first pixel column are connected with one another through at least one first contact hole, the sub lines connected to the second pixel column are connected with one another through at least one second contact hole, and an entire area of the at least one first contact hole is smaller than an entire area of the at least one second contact hole
wherein a resistance of a data line connected to the first pixel column having pixels which each display a same color is provided to be larger than a resistance of a data line connected to the second pixel column which displays the different color from the same color of the first pixel column to decrease a deviation of delay of a data signal between the data line connected to the first pixel column and the data line connected to the second pixel column,
wherein the deviation of delay of the data signal is dependent according to a color emitted by a respective pixel column of the first and second pixel columns.
