    Abstract: A display device includes overlapping two display panels. The display panel on the upper side includes a first display region and a region that transmits visible light. The display panel on the lower side includes a second display region and a region that blocks visible light. The second display region overlaps with the region that transmits visible light. The region that blocks visible light overlaps with the first display region. The display panel on the lower side includes a third display region between the second display region and the region that blocks visible light. The gate signal and the source signal supplied to a first pixel in the third display region are the same as the gate signal and the source signal supplied to a second pixel in the second display region. The second pixel is closer to the first pixel than any other pixels included in the second display region.

    Abstract: A display panel or a display device with high display quality is provided. The display panel includes a light-emitting element, an insulating layer, a protective layer, and a conductive layer. The light-emitting element includes a first electrode, a light-emitting layer, and a second electrode. The light-emitting element emits light to the protective layer side. The insulating layer includes a first opening overlapping with the first electrode. The insulating layer covers an end portion of the first electrode. The light-emitting layer overlaps with the first electrode through the first opening. The second electrode is positioned over the light-emitting layer. The protective layer is over and in contact with the second electrode. The protective layer functions as a protective layer of the light-emitting element. The protective layer includes a second opening overlapping with the insulating layer. The conductive layer is connected to the second electrode through the second opening. The conductive layer functions as an auxiliary wiring of the second electrode.

    Abstract: A display system with high display quality in which display unevenness is reduced is provided. The display system includes a processing unit and a display portion. The processing unit generates second image data by using first image data. The display portion displays an image on the basis of the second image data. The processing unit includes three layers. The first image data is supplied to the first layer. The first image data contains a plurality of pieces of data. The plurality of pieces of data each correspond to any one of the plurality of pixels. The first layer generates first arithmetic data by making the number of data corresponding to one pixel larger than the number of the first image data by using the first image data. The second layer generates second arithmetic data by multiplying the first arithmetic data by a weight coefficient. The third layer generates the second image data by making the number of data corresponding to one pixel smaller than the number of the second arithmetic data by using the second arithmetic data.

    Abstract: A display device with a wide viewing angle is provided. A display device capable of displaying an image with a wide color gamut is provided. A display device includes a first light-emitting element, a second light-emitting element, and a third light-emitting element. The light-emitting elements each include a pair of electrodes and a light-emitting layer. One of the pair of electrodes includes a reflective electrode, and the other of the pair of electrodes includes a transflective electrode. The light-emitting layers of the light-emitting elements are different from each other. A first peak wavelength of the emission spectrum of the first light-emitting element is greater than or equal to 400 nm and less than or equal to 480 nm. A second peak wavelength of the emission spectrum of the second light-emitting element is greater than or equal to 580 nm and less than or equal to 700 nm. A third peak wavelength of the emission spectrum of the third light-emitting element is between the first peak wavelength and the second peak wavelength. The distance between the pair of electrodes of the first light-emitting element is longest and that of the second light-emitting element is second longest.
