1. A display device comprising:
a display area comprising a light-emitting element, the light-emitting element comprising a first electrode, an emission layer and a second electrode;
an encapsulation layer over the light-emitting element, the encapsulation layer comprising:
a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer in order, and
an overlapping area of the first inorganic encapsulation layer and the second inorganic encapsulation layer in direct contact with each other to define an inorganic encapsulation area of the display device;
a supply voltage line electrically connected to the second electrode of the light-emitting element;
a signal line which provides an electrical signal to the display area; and
within the inorganic encapsulation area of the display device:
the signal line overlapping the supply voltage line; and
an etch stop pattern between the supply voltage line and the signal line which overlap each other.
