Abstract
A display device includes a display panel having a first panel and a second panel that face each other with a liquid crystal layer therebetween, a plurality of first sense data lines extending in a row direction on the second panel, a plurality of second sense data lines extending in a column direction on the second substrate, and a sense signal processor. A plurality of sensing units are positioned at regions defined by the first and second sense data lines. A first sense data lines is connected to a second sense data line by a contact to output a first sense data signal through the first sense data line and a second sense data signal through the second sense data line. The sense signal processor reads and processes the first and second sense data signals.
