Provided is a method of manufacturing a display device, in which a defective rate of a display substrate is reduced by, prior to main processing, irradiating a laser to a portion of a processing area of a display substrate, and predicting and correcting a location to which the laser is irradiated. The method includes irradiating a first laser to a first irradiation area of a processing area of a display substrate, obtaining a first image of the processing area of the display substrate, calculating a first displacement between a center of the first irradiation area irradiated with the first laser and a center of the processing area by using the first image, determining a second irradiation area to which a second laser is to be irradiated on the display substrate based on the first displacement, and irradiating the second laser to the second irradiation area.
