Display device

A display device, comprising:

• a substrate;
• a pixel circuit disposed on the substrate;
• a light emitting element including a first electrode electrically connected to the pixel circuit, a light emitting layer disposed on the first electrode, and a second electrode disposed on the light emitting layer;
• a plurality of signal lines disposed on the substrate;
• a first voltage supply line overlapping the signal lines, configured to supply a first voltage to the pixel circuit, and including a first lower conductive layer and a first upper conductive layer disposed on the first lower conductive layer;
• a second voltage supply line overlapping the signal lines, configured to supply a second voltage to the second electrode, and including a second lower conductive layer disposed on a same layer as the first lower conductive layer and a second upper conductive layer disposed on the second lower conductive layer on a same layer as the first upper conductive layer;
• an encapsulation layer disposed on the second electrode the first voltage supply line, and the second voltage supply line;
• and
• a plurality of sensing signal lines disposed on the encapsulation layer,
• wherein the first upper conductive layer and the second lower conductive layer overlap each other.
