Abstract: An electrostatic chuck unit includes a first electrostatic chuck that includes a first plate that includes a surface that is concavely curved in a first direction and a first electrode pattern disposed on the surface of the first plate, and a second electrostatic chuck spaced apart from the first electrostatic chuck in a second direction opposite to the first direction and that includes a second plate that includes a surface adjacent to the first electrostatic chuck and that is convexly curved in the first direction and a second electrode pattern disposed on the surface of the second plate. Each of the first electrode pattern and the second electrode pattern includes an electrode, and a width of the electrode is between 10 mm and 30 mm.

Abstract: A method of fabricating a display device may include disposing a display panel on a stage to be parallel to an XZ-plane defined by a horizontal X-axis and a vertical Z-axis, measuring a height of a first side surface of the display panel in a direction of the Z-axis, rotating the stage such that the first side surface is parallel to a reference horizontal line in case that a result of the measured height indicates that the first side surface includes an inclined surface, moving the display panel in a direction of the Z-axis such that a first pad disposed on the first side surface overlaps the reference horizontal line, and bonding a second pad of a printed circuit board with the first pad.
