Display device

A display device comprising:

• a first conductive layer;
• a second conductive layer;
• a first insulating layer over the first conductive layer and the second conductive layer;
• a first light-emitting element;
• a second light-emitting element;
• and
• a second insulating layer between the first light-emitting element and the second light-emitting element,
• wherein the first light-emitting element comprises:
• a third conductive layer comprising a first region over the first insulating layer and a second region in a first opening provided in the first insulating layer;
• a third insulating layer over the second region;
• and
• a first EL layer comprising a third region over the first region, a fourth region over the second insulating layer, and a fifth region over the third insulating layer,
• wherein the second light-emitting element comprises:
• a fourth conductive layer comprising a sixth region over the first insulating layer and a seventh region in a second opening provided in the first insulating layer;
• a fourth insulating layer over the seventh region;
• and
• a second EL layer comprising an eighth region over the sixth region, a ninth region over the second insulating layer, and a tenth region over the fourth insulating layer,
• wherein the first opening is provided in the first insulating layer so as to reach a top surface of the first conductive layer,
• wherein the second opening is provided in the first insulating layer so as to reach a top surface of the second conductive layer, and
• wherein a top surface of the first region, a top surface of the second insulating layer, a top surface of the third insulating layer, and a top surface of the fourth insulating layer are substantially level with each other.
