Display device

A display device comprising:

• a substrate;
• an encapsulation layer on the substrate;
• in order in a thickness direction from the substrate to the encapsulation layer:
• a signal line;
• a first inorganic insulating layer;
• a first conductive layer;
• a first organic insulating layer;
• a second conductive layer;
• a second organic insulating layer;
• a third conductive layer comprising a supply voltage line which overlaps the signal line to define an overlapping area where the supply voltage line and the signal line overlap each other;
• a third organic insulating layer;
• a light-emitting element comprising a first electrode, an emission layer and a second electrode in order from the substrate, the light-emitting element electrically connected to the supply voltage line;
• and
• the encapsulation layer comprising a first inorganic encapsulation layer, an organic encapsulation layer and a second inorganic encapsulation layer in order in the thickness direction;
• and
• an etch stop pattern corresponding to the overlapping area.

A display device comprising:

• a display area comprising a light-emitting element comprising a first electrode, an emission layer and a second electrode;
• an encapsulation layer over the light-emitting element and comprising a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer;
• 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 overlaps the supply voltage line;
• an etch stop pattern between the supply voltage line and the signal line;
• and
• an inorganic insulating layer between the etch stop pattern and the signal line,
• wherein the inorganic insulating layer comprises:
• a first thickness corresponding to the etch stop pattern, and
• a second thickness outside of the etch stop pattern, the second thickness smaller than the first thickness.
