Classification: CPC H | IPC H

Claim 0:
1. A display device comprising:
a light-emitting element comprising:
a pixel electrode including silver,
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:
a low-resistance area corresponding to the pixel electrode and having an electrical resistance, and
a high-resistance area extended from the low-resistance area, corresponding to the pixel-defining layer and having an electrical resistance which is higher than the electrical resistance of the low-resistance area.
