A manufacturing method of a display device includes irradiating a laser beam onto a work panel along a beam irradiation line corresponding to an outer edge of the display device including a first thickness area and a second thickness area. The irradiating of the laser beam includes first irradiating the laser beam under a first driving condition to provide a first portion of the beam irradiation line at the first area, stopping driving of the laser beam while changing the first driving condition to a second driving condition different from the first driving condition, after the first irradiating of the laser beam, and second irradiating the laser beam under the second driving condition to provide a second portion of the beam irradiation line at the second area, after the stopping of the driving of the laser beam.
