Method for manufacturing display apparatus, display apparatus, display module, and electronic device

A method for manufacturing a display apparatus, comprising:

• forming a first pixel electrode and a second pixel electrode;
• forming an insulating layer covering an end portion of the first pixel electrode and an end portion of the second pixel electrode;
• forming a first layer over the first pixel electrode, the second pixel electrode, and the insulating layer;
• forming a first counter electrode over the first layer;
• placing a first metal mask comprising a first opening over the first counter electrode so that the first opening overlaps the second pixel electrode;
• removing at least part of a region overlapping the second pixel electrode of the first layer and the first counter electrode using the first metal mask;
• forming a second layer over the first pixel electrode, the second pixel electrode, and the insulating layer;
• forming a second counter electrode over the second layer;
• placing a second metal mask comprising a second opening over the second counter electrode so that the second opening overlaps the first pixel electrode;
• removing at least part of a region overlapping the first pixel electrode of the second layer and the second counter electrode using the second metal mask;
• forming, over the first counter electrode and the second counter electrode, a resist mask comprising an opening at a position overlapping the insulating layer;
• exposing part of the insulating layer by removing at least part of a region overlapping the insulating layer of at least one of the first layer, the second layer, the first counter electrode, and the second counter electrode using the resist mask;
• and
• forming a first protective layer covering the first counter electrode, the second counter electrode, and the insulating layer.

A display apparatus comprising:

• a first light-emitting device;
• a second light-emitting device;
• an insulating layer;
• and
• a first protective layer,
• wherein the first light-emitting device comprises a first pixel electrode, a first layer over the first pixel electrode, and a first counter electrode over the first layer,
• wherein the second light-emitting device comprises a second pixel electrode, a second layer over the second pixel electrode, and a second counter electrode over the second layer,
• wherein the first light-emitting device and the second light-emitting device are configured to emit light of different colors from each other,
• wherein the insulating layer covers an end portion of the first pixel electrode and an end portion of the second pixel electrode,
• wherein the first protective layer covers the first light-emitting device, the second light-emitting device, and the insulating layer, and
• wherein the insulating layer comprises a first region overlapping with the first layer, the first counter electrode, the second layer, the second counter electrode, and the first protective layer and a second region in contact with the first protective layer.
