Abstract:
A touch sensor panel according to the present invention includes: a plurality of first electrodes and a plurality of second electrodes, in which 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 multiplying 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.
