Abstract: A touch sensing device including a substrate, a plurality of first sensing series separated from each other and a plurality of second sensing series separated from each other is provided. The substrate has a first surface and a second surface. The first sensing series are disposed on the first surface. Each of the first sensing series includes a plurality of first sensing pads connected to each other. The second sensing series are disposed on the first surface. Each of the second sensing series includes a plurality of second sensing pads distributed between the first sensing series and a plurality of connection lines connecting the second sensing pads. Each of the connection lines extends along an edge of one of the first sensing series, and each of the connection lines is electrically connected to the second sensing pads located at two opposite sides of the first sensing series.
