Abstract
A touch device includes a circuit board, a substrate and a touch-sensing layer. The touch-sensing layer including patterned electrode sets is disposed on the substrate. Each patterned electrode set includes a driving electrode connected to the circuit board and sensing electrodes having wiring lines connected to the circuit board. The wiring lines of each patterned electrode set include first and second groups. The length for one of the wiring lines in the first group is greater than the length for one of the wiring lines in the second group. Diameters of the wiring lines in the first group are greater than diameters of the wiring lines in the second group. The diameter of the longer wiring line is greater than the diameter of the shorter wiring line, in the first group. The diameters in the second group are identical. The total widths of the first and second groups are equal.
