摘要

A display device including display regions with inconspicuous seam is provided. The display device includes a first display panel and a second display panel. The first display panel includes a first display region and a visible-light-transmitting region. The second display panel includes a second display region. The first display region is adjacent to the visible-light-transmitting region. The first display region includes a first light-emitting element and a second light-emitting element. A first common electrode included in the first light-emitting element includes a portion in contact with a second common electrode included in the second light-emitting element. The first common electrode has a function of reflecting visible light. The second common electrode has a function of transmitting visible light. The second light-emitting element is positioned closer to the visible-light-transmitting region than the first light-emitting element. The second display region includes a portion overlapping with the second light-emitting element and a portion overlapping with the visible-light-transmitting region.
