Abstract: According to embodiments of the present disclosure, there may be provided a display device and a driving method thereof. A first subpixel is electrically connected to a first data line and a first reference voltage line, a second subpixel is electrically connected to the first data line and a second reference voltage line different from the first reference voltage line, and magnitudes of a voltage supplied to the first reference voltage line and a voltage supplied to the second reference voltage line are different from each other. Thus, it is possible to efficiently improve a moving picture response time.
