A touch sensing device may include a base substrate, and a first touch electrode including first sensing patterns disposed on the base substrate wherein each first sensing pattern has a shape that is periodically repeated along a first direction, a first dummy pattern disposed between the first sensing patterns on the same layer, and a first dummy connector connecting each first sensing pattern to the first dummy pattern. A first insulation layer is disposed on the first touch electrode, and a second touch electrode including second sensing patterns disposed on the first insulation layer wherein each second sensing pattern has a shape that is periodically repeated along a second direction crossing the first direction, a second dummy pattern disposed between the plurality of second sensing patterns on the same layer, and a second dummy connector connecting each second sensing pattern to the second dummy pattern.
