Display device and fabricating method thereof

A method of fabricating a display device, the method comprising:

• providing a substrate including a display region and a non-display region;
• forming a plurality of transistors in the display region, and forming a pad having a test signal supplied thereto in at least a portion of the non-display region;
• forming a passivation layer over the transistors and the pad;
• forming a display element layer including light emitting elements on the passivation layer;
• and
• forming a touch sensor on the display element layer,
• wherein the forming of the touch sensor includes:
• forming a base layer on the display element layer;
• forming an intermediate layer on the base layer to correspond to the pad;
• forming first bridge patterns on the base layer corresponding to the display region, and forming a cover layer over the intermediate layer;
• forming a first insulating layer over the first bridge patterns and the cover layer;
• forming a plurality of first sensor patterns, a plurality of second sensor patterns, and a plurality of second bridge patterns on the first insulating layer corresponding to the display region;
• and
• forming a second insulating layer over the first sensor patterns, the second sensor patterns, and the second bridge patterns,
• wherein the cover layer is provided in a shape completely covering the intermediate layer.
