1. A display device comprising:
a first subpixel configured to emit light and a second subpixel;
a high-potential voltage line connected to the first subpixel and the second subpixel to deliver a high-potential voltage;
a low-potential voltage line connected to the first subpixel and the second subpixel configured to deliver a low-potential voltage; and
a circuit connected to the low-potential voltage line and configured to sense a value corresponding to the low-potential voltage line during operation of the second subpixel and compensate for a data signal to be supplied to the first subpixel based on the value.
