A compensation device, a display device and a method for compensating common electrode voltage are provided in the embodiments of the present disclosure. A compensation device for a display panel according to an embodiment includes a compensation circuit, a comparison circuit, and an adjustment circuit. The compensation circuit generates a common electrode compensation signal to be provided to the display panel based on a common electrode input signal for providing a common electrode voltage to the display panel and a common electrode feedback signal from the display panel. The comparison circuit compares the common electrode compensation signal with the common electrode feedback signal. The adjustment circuit adjusts the common electrode compensation signal according to the comparison result of the comparison circuit.
