Claim:
1. A method of manufacturing a display device, comprising: preparing a first substrate comprising a first support substrate, a first display element part including a first display element, a first extension part including a first mounting portion, a second display element part including a second display element, and a second extension part including a second mounting portion, the first display element part and the first extension part being located in a first region above the first support substrate, and the second display element part and the second extension part being located in a second region neighboring the first region above the first support substrate; preparing a second substrate comprising a second support substrate, a first peeling auxiliary layer opposed to the first display element part, a second peeling auxiliary layer opposed to the second display element part and spaced apart from the first peeling auxiliary layer, and a sacrifice layer opposed to the first extension part and the second extension part, the first peeling auxiliary layer, the second peeling auxiliary layer, and the sacrifice layer being located above the second support substrate; attaching the first substrate to the second substrate in a state in which the first extension part and the second extension part are opposed to the sacrifice layer, the first display element part is opposed to the first peeling auxiliary layer, and the second display element part is opposed to the second peeling auxiliary layer; and radiating a laser beam on the second substrate, and peeling the second support substrate from the first peeling auxiliary layer and the second peeling auxiliary layer while blocking the laser beam by the sacrifice layer.
