Display device with overlapping touch sensor improving touch performance by decreasing coupling capacitance generated between power supply line and outer lines

A display device comprising:

• a substrate corresponding to a display area in which an image is displayed, and a non-display area at at least one side of the display area;
• a touch sensing device at the display area;
• first outer lines electrically connected to the touch sensing device, and located at a first non-display area that is a first portion of the non-display area;
• second outer lines connecting the first outer lines and the touch sensing device;
• a plurality of pixels at the display area;
• a driving circuit at the first non-display area for driving the pixels, and comprising a data driver for supplying a data signal to the pixels through respective data lines;
• a power supply line electrically connected to the pixels and located at a second non-display area that is a second portion of the non-display area;
• and
• a power supply for supplying power to the pixels through the power supply line,
• wherein the power supply line is separate and distinct from the data lines,
• wherein the power supply line surrounds the display area, and
• wherein the power supplied to the pixels is different from the data signal supplied to the pixels.
