Display apparatus and manufacturing method of the display apparatus

A display apparatus comprising:

• a first light-emitting element;
• and
• a second light-emitting element,
• wherein in the first light-emitting element, a first pixel electrode, a first light-emitting layer, a first intermediate layer, a third light-emitting layer, and a common electrode are stacked in this order,
• wherein in the second light-emitting element, a second pixel electrode, a second light-emitting layer, a second intermediate layer, a fourth light-emitting layer, and the common electrode are stacked in this order,
• wherein a first layer, a second layer, a third layer, and a fourth layer are included between the first light-emitting element and the second light-emitting element,
• wherein the first layer overlaps with the second light-emitting layer, the second intermediate layer, and the fourth light-emitting layer and comprises a material that is the same as a material of the first light-emitting layer,
• wherein the second layer overlaps with the first light-emitting layer, the first intermediate layer, and the third light-emitting layer and comprises a material that is the same as a material of the second light-emitting layer,
• wherein the third layer overlaps with the first layer and comprises a material that is the same as a material of the third light-emitting layer,
• wherein the fourth layer overlaps with the second layer and comprises a material that is the same as a material of the fourth light-emitting layer,
• wherein an end portion of the first light-emitting layer and an end portion of the first layer are provided to face each other in a region between the first light-emitting element and the second light-emitting element,
• wherein an end portion of the second light-emitting layer and an end portion of the second layer are provided to face each other in the region between the first light-emitting element and the second light-emitting element,
• wherein an end portion of the third light-emitting layer and an end portion of the third layer are provided to face each other in the region between the first light-emitting element and the second light-emitting element, and
• wherein an end portion of the fourth light-emitting layer and an end portion of the fourth layer are provided to face each other in the region between the first light-emitting element and the second light-emitting element.

A manufacturing method of a display apparatus, comprising:

• a first step of forming a first pixel electrode and a second pixel electrode side by side;
• a second step of forming an island-shaped first light-emitting layer over the first pixel electrode with use of a first metal mask;
• a third step of forming an island-shaped second light-emitting layer over the second pixel electrode with use of a second metal mask, the second light-emitting layer overlapping with an end portion of the first light-emitting layer;
• a fourth step of dividing each of the first light-emitting layer and the second light-emitting layer by etching in a region between the first pixel electrode and the second pixel electrode;
• and
• a fifth step of forming a common electrode covering the first light-emitting layer and the second light-emitting layer.
