A touch panel device and a method for detecting a contact position are provided. The touch panel device includes a touch panel including a first touch pattern, the first touch pattern having a plurality of first touch pads connected in series; and a touch sensor for applying a clock signal to one terminal of the first touch pattern, receiving a first delayed clock signal from the other terminal of the first touch pattern, and generating contact position data corresponding to a contact position of an object using a difference in delay time between the clock signal and the first delayed clock signal. Thus, since the plurality of touch pads are connected in series, the contact position of the entire touch panel can be sensed with only one touch sensor, and the touch pad has a greater area than the connection line for a distinguished difference in resistance between the touch pad and the connection line, such that the contact position can be accurately detected.
