An apparatus for eliminating image sticking, a display device and a method for eliminating image sticking. The apparatus for eliminating image sticking comprises a Multi-Level Gate (MLG) circuit (1) and a gate driving module (2), the MLG circuit (1) is configured to receive a gate ON voltage unmodulated and output a modulated gate ON voltage according to an enable signal; the gate driving module (2) receives the gate ON voltage unmodulated and the modulated gate ON voltage outputted from the MLG circuit, and outputs one of the gate ON voltage unmodulated and the modulated gate ON voltage for each layer of gate lines among different layers of gate lines. No change in process on a panel side is required and a short period of time is taken to eliminate the image sticking. The image sticking eliminating effect is controllable because a gate signal and its falling time are controllable, and the image sticking eliminating is more flexible.
