Classification: CPC H | IPC H

Claim 14:
15. A display device comprising:
a light-emitting element comprising:
a pixel electrode,
a common electrode facing the pixel electrode, and
an emission layer between the pixel electrode and the common electrode,

a pixel-defining layer which is between the pixel electrode and the emission layer and exposes the pixel electrode to outside the pixel-defining layer; and
a barrier layer which is between the pixel-defining layer and the emission layer, the barrier layer comprising:
indium gallium zinc oxide or indium tin zinc oxide,
an n+ doped first area which has an electrical resistance, and
a second area which extends from the n+ doped first area and has an electrical resistance which is different from the electrical resistance of the n+ doped first area.
