Abstract: Provided are a laser processing method capable of performing various types of processing while reducing a need to change components and method of manufacturing a display apparatus by using the laser processing method. The laser processing method includes: splitting a laser beam emitted from a laser beam source into a plurality of laser beams by using a laser beam splitter; and transmitting at least two of the plurality of laser beams through a position adjustment equipment that is on paths of the at least two laser beams in order to adjust a distance between the at least two laser beams by using a difference between a refractive index of an element of the position adjustment equipment and a refractive index of a peripheral environment.
