Abstract

A novel display panel that is highly convenient, useful, or reliable is provided. The display panel includes a first light-emitting device, a second light-emitting device, a partition, a first protective layer, and a second protective layer. The first light-emitting device includes a first electrode, a second electrode, and a first layer, and the first layer is interposed between the electrodes. The first layer includes a first material having a hole-transport property and a first substance having an electron-accepting property, and the first protective layer is in contact with the second electrode. The second light-emitting device includes a third electrode, a fourth electrode, and a second layer, and the second layer is interposed between the electrodes. The second layer includes the first material having a hole-transport property and the first substance having an electron-accepting property, and the second layer includes a first gap between the second layer and the first layer. The second protective layer includes a second gap between the second protective layer and the first protective layer. The second gap overlaps with the first gap, and the second protective layer is in contact with the fourth electrode. The partition overlaps with the first gap and the second gap.
