Abstract: A display device includes a display substrate comprising a polymer layer including a first non-bending area, a second non-bending area that overlaps the first non-bending area when viewed in a plan view, and a bending area arranged between the first non-bending area and the second non-bending area. A display element layer is disposed on the polymer layer. A plurality of signal pad groups is disposed in the second non-bending area and is configured to be electrically connected to the display element layer. An upper substrate is disposed on a top surface of the display substrate. A flexible circuit board comprising a plurality of connection pad groups is arranged in correspondence to the signal pad groups. An area of the upper substrate is larger than an area of the display substrate when viewed in a plan view.

Abstract: A tiled display device includes a plurality of display panel modules arranged adjacent to each other. Each of the plurality of display panel modules includes a display panel including a display area and a bezel area at least partially surrounding the display area, a light blocking layer disposed on the display panel and extending from the display area to a portion of the bezel area, and a protective layer disposed on the light blocking layer. In the bezel area, a distance from an end of the display panel to an end of the protective layer is greater than a distance from the end of the display panel to an end of the light blocking layer. Accordingly, an air layer is not formed between the protective layer and the display panel. A visibility of a seam area is reduced.
