Display device including a touch line connected to touch electrodes that overlaps a power supply line

A display device comprising:

• a substrate;
• a first active layer disposed on the substrate and including a channel region;
• a first gate insulating film disposed on the first active layer;
• a first gate electrode disposed on the first gate insulating film and overlapping the channel region of the first active layer;
• a first interlayer insulating film disposed on the first gate electrode;
• a capacitor electrode disposed on the first interlayer insulating film and overlapping the first gate electrode;
• a second interlayer insulating film disposed on the capacitor electrode;
• a first sub power supply line and a third sub power supply line disposed on the second interlayer insulating film;
• a second sub power supply line disposed on the first sub power supply line;
• a fourth sub power supply line disposed on the third sub power supply line;
• a fifth sub power supply line disposed on the second sub power supply line;
• and
• a first planarization film disposed between the third sub power supply line and the fourth sub power supply line,
• wherein at least one of the first sub power supply line and the fifth sub power supply line overlaps at least one of the third sub power supply line and the fourth sub power supply line.

A display device comprising:

• a substrate including a display area and a non-display area;
• touch electrodes disposed in the display area;
• touch lines disposed in the non-display area and connected to the touch electrodes;
• a first power supply line disposed in the non-display area and having a first power supply voltage applied thereto, the first power supply line including a first sub power supply line disposed on the substrate, a second sub power supply line disposed on the first sub power supply line, and a fifth sub power supply line disposed on the second sub power supply line;
• a second power supply line disposed in the non-display area and having a second power supply voltage applied thereto, the second power supply voltage being higher than the first power supply voltage and wherein the second power supply line includes a third sub power supply line disposed on the substrate, and a fourth sub power supply line;
• a first planarization film between the third sub power supply line and the fourth sub power supply line;
• a second planarization film disposed on the fourth sub power supply line, wherein the fifth sub power supply line is disposed on the second planarization film;
• a dam disposed on the first sub power supply line and the second sub power supply line;
• a mask support structure;
• and
• an inorganic encapsulation area between the dam and the mask support structure, and
• wherein the second sub power supply line overlaps the mask support structure, and
• wherein the second sub power supply line is disposed in the inorganic encapsulation area,
• wherein any one of the touch lines overlaps at least one of the first power supply line and the second power supply line, and
• a portion of the first power supply line overlaps a portion of the second power supply line.
