摘要： A display device includes a display panel in which first holes arranged in a first direction and a second direction that intersects the first direction are defined, and a first panel bottom member which is disposed on one surface of the display panel and in which second holes arranged in the first and second directions are defined. A maximum length of a second hole among the second holes in the first direction satisfies “e×(a+c)” where a denotes a maximum length of a first hole among the first holes in the first direction, c denotes a minimum distance between neighboring first holes among the first holes in the first direction, and e is a positive integer.

摘要： A glass substrate has a first surface, a second surface opposite to the first surface, and a thickness from the first surface to the second surface. The glass substrate includes a first region, a second region, and a third region. The first region extends from the first surface a first depth into the glass substrate and has a first compressive stress. The second region extends from the second surface a second depth into the glass substrate and has a second compressive stress different from the first compressive stress. The third region is between the first region and the second region. In the glass substrate, the first compressive stress has a maximum value at a location between the first surface and the first depth, and the second compressive stress has a maximum value at a location between the second surface and the second depth.

摘要： A tiled display comprises display devices adjacent to one another and each comprising first pixels and second pixels, a first boundary area where longer sides of at least two of the display devices are adjacent to each other, and a second boundary area where shorter sides of at least two of the display devices are adjacent to each other. Each of the first pixels and the second pixels comprises sub-pixels. The first pixels are disposed in the first boundary area such that the sub-pixels of the first pixels are parallel to the longer sides of the display devices. The second pixels are disposed in the second boundary area such that the sub-pixels of the second pixels are parallel to the shorter sides of the display devices.
