Display device

The present application relates to a display device comprising: an upper display substrate comprising a first pixel region for emitting first light, a second pixel region for emitting second light different from the first light, and a third pixel region for emitting third light different from the first light and the second light; and a lower display substrate including a first light emitting element overlapping the first pixel region, a second light emitting element overlapping the second pixel region, and a third light emitting element overlapping the third pixel region. The second light-emitting element comprises one or more first stacks for emitting the second light, and the third light-emitting element comprises one or more second stacks for emitting the third light, and a concentration of conductive material contained in the one or more first stacks is higher than a concentration of conductive material contained in the one or more second stacks. 本申请涉及显示装置，所述显示装置包括：上显示衬底，其包括用于发射第一光的第一像素区、用于发射不同于所述第一光的第二光的
