Abstract:
1. A light-emitting device comprising: a first light-emitting element over a substrate; a second light-emitting element adjacent to the first light-emitting element over the substrate; and an insulating pattern between the first light-emitting element and the second light-emitting element over the substrate, wherein the first light-emitting element comprises a stacked layer of a first lower electrode layer, a first EL layer, and a first upper electrode layer, wherein the second light-emitting element comprises a stacked layer of a second lower electrode layer, a second EL layer, and a second upper electrode layer, wherein the insulating pattern comprises a leg portion and a stage portion over the leg portion, wherein the stage portion projects beyond the leg portion in a direction parallel to the substrate, wherein the first lower electrode layer and the second lower electrode layer are formed from the same layer, wherein the first EL layer and the second EL layer are formed from the same layer and are separated by the insulating pattern, and wherein the first upper electrode layer and the second upper electrode layer are formed from the same layer and are separated by the insulating pattern.
