Abstract

A touch device is provided, including a first substrate and a circuit substrate. The first substrate includes a touch sensing structure and a plurality of first electrodes. The touch sensing structure is disposed on the first substrate. The first electrodes are arranged along a first direction. The first electrodes are disposed on the first substrate and electrically connected to the touch sensing structure, a first gap is formed between two adjacent first electrodes, and a minimum distance between the two adjacent first electrodes is a gap distance. The circuit substrate is partially overlapping the substrate in a vertical projection direction, the circuit substrate including a plurality of second electrodes corresponding to the first electrodes. One of the two adjacent first electrodes has a first electrode side edge facing the first gap. One of the second electrodes has a second electrode side edge located in the first gap.
