Touch sensor and touch panel having the same

A touch panel, comprising:

• a light-transmissive cover;
• a display module disposed on the light-transmissive cover;
• and
• a touch sensing layer disposed between the light-transmissive cover and the display module, wherein the touch sensing layer has a first side and a second side opposite to the first side, the first side has a first folding region, and the second side has a second folding region, wherein when the first side and the second side of the touch sensing layer are unfolded, the first folding region and the second folding region extend outward from two opposite edges of the light-transmissive cover;
• and when the first side and the second side of the touch sensing layer are folded, the first folding region and the second folding region are located on the display module, and wherein when the first folding region and the second folding region are folded, the light-transmissive cover, the touch sensing layer, and the display module collectively form a first projection area, and when the first side and the second side are unfolded, the light-transmissive cover and the touch sensing layer collectively form a second projection area that is larger than the first projection area.
