Display apparatus, display module, electronic device, and method of manufacturing display apparatus

A display apparatus comprising:

• a first light-emitting device;
• a second light-emitting device;
• an insulating layer;
• and
• a first sidewall,
• wherein the first light-emitting device comprises a first pixel electrode, a first light-emitting unit over the first pixel electrode, a first charge-generation layer over the first light-emitting unit, a second light-emitting unit over the first charge-generation layer, and a common electrode over the second light-emitting unit,
• wherein the second light-emitting device comprises a second pixel electrode, a third light-emitting unit over the second pixel electrode, a second charge-generation layer over the third light-emitting unit, a fourth light-emitting unit over the second charge-generation layer, and the common electrode over the fourth light-emitting unit,
• wherein each of an end portion of the first pixel electrode and an end portion of the second pixel electrode is covered with the insulating layer,
• wherein the first light-emitting device and the second light-emitting device are configured to emit light of different colors, and
• wherein the first sidewall covers at least a side surface of the first charge-generation layer.
