Abstract: Disclosed herein are a display device, an apparatus for testing a display device, and a method for testing a display device. A display device includes a first substrate having a display area and a non-display area defined thereon, the non-display area being on an outer side of the display area. The non-display area may include a plurality of test pads and a first dummy thin-film transistor electrically connected to the test pads. The first dummy thin-film transistor includes a dummy gate electrode, and a dummy source electrode and a dummy drain electrode insulated from the gate electrode and spaced apart from each other. A bending area is defined on the first substrate that at least partially traverses the display area and the non-display area, the bending area overlaps the first dummy thin-film transistor.

Abstract: A display device is provided. The display device includes a display panel including a folding region, first and second non-folding regions at opposite sides of the folding region; a first support plate below the display panel to overlap the first non-folding region and to partially overlap the folding region; a second support plate below the display panel to overlap the second non-folding region and to partially overlap the folding region; a first plate coupling film between the display panel and the first support plate to overlap the first non-folding region; a second plate coupling film between the display panel and the second support plate to overlap the second non-folding region; a first step compensating member between the display panel and the first support plate to overlap the folding region, apart from the first plate coupling film, and including a light shielding layer; and a second step compensating member between the display panel and the second support plate to overlap the folding region, apart from the second plate coupling film, and including a light shielding layer.
