PROBLEM TO BE SOLVED: To provide a large-sized display device, and to provide a display device that allows displays with a wide color gamut.SOLUTION: Provided is a display device having a plurality of display panels. A first display panel has a first display region. A second display panel has a second display region and a region transmitting visible light. The second display region is adjacent to the region transmitting visible light. The first display region has a part overlapped with the region transmitting visible light. The first display panel has a plurality of light-emitting elements. With respect to light emission from a first light-emitting element, a chromaticity x on CIE1931 chromaticity coordinates is larger than 0.680 and equal to or less than 0.720, and a chromaticity y is equal to or more than 0.260 and equal to or less than 0.320. Similarly, with respect to light emission from a second light-emitting element, the chromaticity x is equal to or more than 0.130 and equal to or less than 0.250, and the chromaticity y is larger than 0.710 and equal to or less than 0.810. With respect to light emission from a third light-emitting element, the chromaticity x is equal to or more than 0.120 and equal to or less than 0.170, and the chromaticity y is equal to or more than 0.020 and less than 0.060.SELECTED DRAWING: Figure 2 【課題】大型の表示装置を提供する。広色域での表示が可能な表示装置を提供する。【解決手段】複数の表示パネルを有する表示装置である。第１の表示パネルは、第１の表示領域を有する。第２の表示パネルは、第２の表示領域及び可視光を透過する領域を有する。第２の表示領域は、可視光を透過する領域と隣接する。第１の表示領域は、可視光を透過する領域と重なる部分を有する。第１の表示パネルは、複数の発光素子を有する。第１の発光素子からの発光は、ＣＩＥ１９３１色度座標における色度ｘが０．６８０より大きく０．７２０以下、色度ｙが０．２６０以上０．３２０以下である。同様に、第２の発光素子からの発光は、色度ｘが０．１３０以上０．２５０以下、色度ｙが０．７１０より大きく０．８１０以下であり、第３の発光素子からの発光は、色度ｘが０．１２０以上０．１７０以下、色度ｙが０．０２０以上０．０６０未満である。【選択図】図２
