Abstract: A touch sensing unit, includes a plurality of first sensing electrodes and a plurality of second sensing electrodes intersecting with and insulated from the plurality of first sensing electrodes. The plurality of first sensing electrodes includes a plurality of first sensor portions and a plurality of first connection portions connecting each of the plurality of first sensor portions with one another. The plurality of second sensing electrodes includes a plurality of second sensor portions, a plurality of stem sensors extended from the plurality of second sensor portions, and a plurality of second connection portions connecting each of the plurality of sensor portions with one another. Each of the plurality of first sensor portions includes a plurality of depressions indented inwardly. Each of the plurality of stem sensors is disposed such that it is at least partially surrounded by a respective depression of the plurality of depressions.
