Touch sensor panel and touch input device with reduced magnitude of low ground mass interference signal

A touch sensor panel comprising:

• a plurality of first electrodes and a plurality of second electrodes,
• wherein a touch window area includes a first number of consecutive first electrodes in a first direction among the plurality of first electrodes and a second number of consecutive second electrodes in a second direction with respect to at least one of the first number of first electrodes to correspond to each other, and
• a value acquired by a multiplication of the number of unit cells constituting at least one first electrode connected to a first trace among the first electrodes included in the touch window area and the number of unit cells constituting at least one second electrode connected to a second trace among the second electrodes included in the touch window area is less than a predetermined value,
• wherein a pair of a predetermined first electrode among the first electrodes included in the touch window area and a predetermined second electrode among the second electrodes do not exist in other window areas other than the touch window area.
