Abstract

Provided is a display apparatus having high display quality. This display apparatus has a first light-emitting device, a second light-emitting device, a first insulating layer, and a filler layer. The first light-emitting device has a first electrode, a first semiconductor layer on the first electrode, and a shared electrode on the first semiconductor layer. The second light-emitting device has a second electrode, a second semiconductor layer on the second electrode, and the shared electrode on the second semiconductor layer. The first insulating layer has a region that is in contact with a side surface of the first semiconductor layer and a side surface of the second semiconductor layer. The filler layer has a region that overlaps with the side surface of the first semiconductor layer and the side surface of the second semiconductor layer, with the first insulating layer therebetween. The shared electrode has a region that is in contact with the top surface of the filler layer.
