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. ## Claims ### Claim 1 A display device comprising: a display panel comprising a display region comprising a first pixel and a second pixel, wherein the first pixel is an outermost pixel in the display region and the second pixel is adjacent to the first pixel and not outermost in the display region, wherein: the first pixel and the second pixel each comprise a display element; the first pixel is electrically connected to a signal line and a scan line; and the second pixel is electrically connected to the signal line and the scan line. ### Claim 2 (depends on 1) The display device according to claim 1, wherein the first pixel and the second pixel each comprise a first transistor electrically connected to the signal line and the scan line. ### Claim 3 (depends on 1) The display device according to claim 1, wherein the display element is a light-emitting element. ### Claim 4 (depends on 3) The display device according to claim 3, wherein the light-emitting element comprises a light-emitting layer comprising an organic compound. ### Claim 5 (depends on 1) The display device according to claim 1, wherein: the display panel comprises a region surrounding the display region; and the region comprises: a first region capable of transmitting visible light; and a second region capable of blocking visible light. ### Claim 6 (depends on 1) The display device according to claim 1, wherein: the display element comprises a pixel electrode; a size of the pixel electrode in the first pixel is different from a size of the pixel electrode in the second pixel. ### Claim 7 A display device comprising: a display panel comprising a display region comprising a first pixel and a second pixel, wherein the first pixel is an outermost pixel in the display region and the second pixel is adjacent to the first pixel and not outermost in the display region, wherein the first pixel is configured to simultaneously display an image same as an image displayed in the second pixel. ### Claim 8 (depends on 7) The display device according to claim 7, wherein the first pixel and the second pixel each comprise a first transistor electrically connected to the same signal line and the same scan line. ### Claim 9 (depends on 7) The display device according to claim 7, wherein the first pixel and the second pixel each comprise a light-emitting element. ### Claim 10 (depends on 9) The display device according to claim 9, wherein the light-emitting element comprises a light-emitting layer comprising an organic compound. ### Claim 11 (depends on 7) The display device according to claim 7, wherein: the display panel comprises a region surrounding the display region; and the region comprises: a first region capable of transmitting visible light; and a second region capable of blocking visible light. ### Claim 12 (depends on 7) The display device according to claim 7, wherein: the first pixel and the second pixel each comprise a pixel electrode; a size of the pixel electrode in the first pixel is different from a size of the pixel electrode in the second pixel.
