Abstract:
1. A method of manufacturing a display apparatus, the method comprising: arranging, on a mounting unit, a substrate which has an amorphous silicon layer; arranging a first mark mask and a second mark mask respectively on a first part and a second part of the amorphous silicon layer of the substrate; adjusting a location of the first mark mask relative to a first image module and adjusting a location of the second mark mask relative to a second image module; and radiating a laser beam to the first mark mask, to the second mark mask, and to at least a part of areas of the amorphous silicon layer of the substrate that do not correspond to the first mark mask and the second mark mask, thereby changing the areas of the amorphous silicon layer of the substrate to which a laser beam is radiated to crystalline silicon.
