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: By controlling the optical thickness of the upper stacked structure disposed on the display panel, it is possible to periodically control the tristimulus value of Xr and the tristimulus value of Yg emitted from the electronic device. The optical thickness is determined by the thickness and refractive index of the upper stacked structure. This control may reduce the tristimulus value of Xr periodically or increase the tristimulus value of Yg periodically. The tristimulus value of Xr may be periodically decreased and the tristimulus value of Yg may be periodically increased at the same time.
