Abstract: A display device includes a display panel in which a first region, a second region, and a third region are defined along a first direction, a window module disposed on the display panel, and including a window substrate, a coating member covering a side surface of the display panel and a side surface of the window module, and a lower substrate disposed under the display panel. A side surface of the window substrate is disposed more inwardly than the side surface of the display panel is, and a side surface of the coating member is connected to the lower substrate.

Abstract: A display device includes a display area and a non-display area including a first driving pad portion at which a display panel is connected to an integrated circuit chip by a solder bump having a width. The first driving pad portion includes a first pad through which an electrical signal transmits between the first driving pad portion and the integrated circuit chip, and a second pad by which alignment between the first driving pad portion and the integrated circuit chip is determined. The second pad of the first driving pad portion includes a (2-1)-th pad having a width which is the same as the width of the solder bump and a (2-2)-th pad having a width which is larger than the width of the (2-1)-th pad.

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.
