Abstract: A display device includes a display panel and a backlight unit adjacent to the display panel. A cover unit is adjacent to the display panel and the backlight unit. The backlight unit includes a light guiding structure including a first surface and a second surface facing each other in a thickness direction of the display panel. Side surfaces connect the first surface to the second surface. Signal lines are directly disposed on the first surface, the second surface, or a side surface of the side surfaces. A light-emitting diode package is coupled to the signal lines and is positioned to provide light to a. first side surface of the side surfaces.

Abstract: A cover layer manufacturing method includes: a first applying process, which forms a first cover layer on a rear surface of a first display panel using a first mask in an applying unit; a first cleaning process, which cleans a second mask in a cleaning unit; a rotating process, which changes a position of the first mask and a position of the second mask using a rotation driver; a second applying process, which forms a second cover layer on a rear surface of a second display panel using the second mask in the applying unit; and a second cleaning process, which cleans the first mask in the cleaning unit. The first applying process and the first cleaning process are substantially simultaneously performed, and the second applying process and the second cleaning process are substantially simultaneously performed.

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.
