1. A display device comprising:
a display panel which operates in a sensing mode or an emission mode;
a data driver electrically connected to the display panel; and
a compensation part electrically connected to the data driver,
wherein the display panel includes:
a first pixel;
a second pixel spaced from the first pixel in a first direction;
a third pixel spaced from the second pixel in the first direction;
a fourth pixel spaced from the third pixel in the first direction;
a fifth pixel spaced from the first pixel in a second direction crossing the first direction;
a sixth pixel spaced from the second pixel in the second direction;
a first scan line electrically connected to the first pixel and the third pixel;
a second scan line electrically connected to the sixth pixel;
a first data line electrically connected to the first pixel, the second pixel, the fifth pixel, and the sixth pixel; and
a second data line electrically connected to the third pixel and the fourth pixel,
wherein the data driver includes:
a first switch electrically connected to the first pixel and the second pixel; and
a second switch electrically connected to the third pixel and the fourth pixel,
wherein the sensing mode includes:
a first period in which a first scan signal is provided to the first scan line and the first switch is turned on; and
a second period in which the first scan signal is provided to the first scan line and the second switch is turned on, and
wherein the compensation part compensates for image data, which is to be provided to the second pixel, based on a voltage sensed in each of the first pixel, the third pixel, and the sixth pixel.
