Display panel, data processing device, and manufacturing method of the display panel

A display panel comprising:

• a first light-emitting device;
• a second light-emitting device;
• a partition;
• a first protective layer;
• and
• a second protective layer,
• wherein the first light-emitting device comprises a first electrode, a second electrode and a first layer,
• wherein the first layer comprises a region interposed between the second electrode and the first electrode,
• wherein the first layer comprises a first material having a hole-transport property and a first substance having an electron-accepting property,
• wherein the first layer has an electrical resistivity higher than or equal to 1×102 Ωcm and lower than or equal to 1×108 Ωcm,
• wherein the first protective layer is in contact with the second electrode,
• wherein the second electrode is interposed between the first protective layer and the first electrode,
• wherein the second light-emitting device comprises a third electrode, a fourth electrode and a second layer,
• wherein the second layer comprises a region interposed between the fourth electrode and the third electrode,
• wherein the second layer comprises the first material having a hole-transport property and the first substance having an electron-accepting property,
• wherein the second layer comprises a first gap between the second layer and the first layer,
• wherein the second protective layer comprises a second gap between the second protective layer and the first protective layer,
• wherein the second gap overlaps with the first gap,
• wherein the second protective layer is in contact with the fourth electrode,
• wherein the fourth electrode is interposed between the second protective layer and the third electrode,
• wherein the partition comprises a first opening portion and a second opening portion,
• wherein the first opening portion overlaps with the first electrode,
• wherein the second opening portion overlaps with the third electrode, and
• wherein the partition overlaps with the first gap and the second gap between the first opening portion and the second opening portion.
