Digitizer and display device including the same

A display device in which a folding area folded with respect to an imaginary folding axis extending in a first direction, a first non-folding area, and a second non-folding area spaced apart from the first non-folding area with the folding area interposed therebetween are defined, the display device comprising:

• a digitizer;
• a display panel disposed on the digitizer;
• and
• a window disposed on the display panel, the digitizer comprising:
• a first base layer;
• a second base layer disposed on the first base layer;
• a third base layer disposed on the second base layer;
• a first sensing line disposed between the first base layer and the second base layer and extending in the first direction;
• and
• a second sensing line extending in a second direction substantially perpendicular to the first direction, disposed between the second base layer and the third base layer, and comprising:
• a first sub-line portion disposed in the first non-folding area;
• a second sub-line portion disposed in the second non-folding area;
• and
• a third sub-line portion disposed between the first sub-line portion and the second sub-line portion to correspond to the folding area,
• wherein the third sub-line portion has a fracture strain greater than a fracture strain of the first sub-line portion and the second sub-line portion.
