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.

Abstract: A display device includes a backlight assembly and a display panel which displays an image. The backlight assembly includes a light emitting unit which generates light, and an optical member which adjusts a path of the light incident thereto and outputs the light toward the display panel. The optical member includes a first base film to which the light is incident, a second base film closer to the display panel than the first base film and for which are defined first and second areas alternately disposed, a first optical pattern between the first and second base films at the first area, where the first optical pattern refracts therein the light incident to the first base film, and a second optical pattern between the first and second base films at the second area, where the second optical pattern scatters the light incident to the first base film.
