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.

說明書

The light-transmitting layer 318 can overlap with part or the whole of a surface of the substrate 371 of the lower display panel. Furthermore, the light-transmitting layer 318 can overlap with part or the whole of a surface of the substrate 361 of the upper display panel. For example, the light-transmitting layer 318 may overlap with only the visible-light-transmitting region 72a and the display region 71b. The light-transmitting layer 318 may overlap with the driver circuit 78b.

Next, specific examples of the display panel of one embodiment of the present invention, which are different from the display panels 370A, 370B, and 370C, will be described with reference to FIG. 9 and FIG. 10.

FIG. 9(A) and FIG. 10(A) are cross-sectional views of a display panel 370D. FIG. 9(B) and FIG. 10(B) are cross-sectional views of a display panel 370E. FIGS. 9(A) and 9(B) correspond to cross-sectional views along dashed-dotted line C1-C2 in FIG. 5(A). FIGS. 10(A) and 10(B) correspond to cross-sectional views along dashed-dotted line C3-C4 in FIG. 5(A).
