Abstract: A method of manufacturing a display and a chemical mechanical polishing method which employ a chemical mechanical polishing apparatus that includes a conveyor belt to transfer a substrate, a polishing head disposed on the conveyor belt, and a body part which moves the polishing head and supplies a slurry to the polishing head. The polishing head includes a first polishing part including a first polishing pad surrounding a first slurry outlet, and a second polishing part surrounding the first polishing part and including a second polishing pad. A second slurry outlet is formed between the first polishing part and the second polishing part, and the first polishing part and the second polishing part are movable independently of each other in a direction substantially perpendicular to the substrate.
