Abstract
A direction detection device, according to one embodiment of the present invention, comprises: a dielectric layer; a first electrode layer which is arranged on a first surface of the dielectric layer, and which comprises a plurality of first electrode patterns arranged in a first direction; a second direction arranged on a second surface of the dielectric layer, which faces the first surface; a capacitance detection unit which detects changes in capacitance due to time difference between a first region and a second region, wherein in the first region, at least one selected among the plurality of first electrode patterns overlaps the second electrode layer, and in the second region, at least one selected from the plurality of the remaining first electrode patterns overlaps the second electrode layer; and a direction detection unit which connects to the capacitance detection unit, and detects a movement direction on the basis of the time difference between the first region and the second region.
