Abstract: A substrate-cutting method includes preparing a first substrate in which a plurality of first active areas spaced apart from each other and a first non-active area surrounding the first active areas are defined in a plane, forming an adhesive layer on the first substrate where the adhesive layer is disposed within the first active areas, disposing a second substrate in which a plurality of second active areas spaced apart from each other and a second non-active area surrounding the second active areas are defined in the plane, and cutting a cutting line of the second substrate, which corresponds to a boundary between the second active areas and the second non-active area, using a laser beam. The adhesive layer does not overlap the cutting line of the second substrate.

Abstract: A method of manufacturing a display device includes preparing a preliminary foldable module including a window module, a display panel disposed on the window module, a panel protective layer disposed on the display panel, and a support plate disposed on the panel protective layer. Performing a first cutting operation including cutting the support plate with a first laser beam. Detecting, by a laser-sensing part, reflected light that is reflected from a surface of the panel protective layer exposed by cutting the support plate and changing the first laser beam to a second laser beam. Performing a second cutting operation of sequentially cutting the panel protective layer, the display panel, and the window module with the second laser beam.

Abstract: 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.

Abstract: A display device fabrication method includes providing a substrate including a display panel including a panel mark, placing a processing module on the display panel, the processing module including a processing mark and a first processing line adjacent to the processing mark, the processing mark corresponding to the panel mark of the display panel, calculating an offset between the panel mark and the processing mark, correcting the first processing line to define a second processing line overlapping a periphery of the display panel, the correcting including reflecting the calculated offset, and processing the periphery of the display panel along the second processing line. The calculating of the offset includes obtaining a first offset defined as a displacement between points on the processing and panel marks, and obtaining a second offset defined as an angle of the panel mark with respect to the processing mark.

Abstract: An electronic apparatus which is divided into a folding region foldable with respect to a folding axis extending in a direction, a first non-folding region adjacent to a side of the folding region, and a second non-folding region adjacent to another side of the folding region includes a lower module, a display panel disposed on the lower module, and a window disposed on the display panel. In a first cross-sectional view parallel to a thickness direction of the display panel and perpendicular to the folding axis, a first side surface of the display panel is inclined with respect to a lower surface of the display panel. Accordingly, the electronic apparatus may exhibit excellent display quality.
