Abstract: A touch sensor driving circuit (210) includes a driving circuit (211) for applying a driving signal to first touch electrodes (TX) arranged in a display area (AA) through a plurality of TX wires (TXL); and a sensing circuit (212) for sensing voltages of second touch electrodes (RX) arranged in first and second regions (A1, A2) within the display area (AA) through first and second RX wires (RXL, RXL), respectively, the voltages being generated by the driving signal. The sensing circuit (212) may amplify or integrate a voltage difference between a voltage sensed through one nth (where n is a natural number) RX (RXLn) wire positioned closest to TX wires (TXL) located at opposite outermost sides of the plurality of TX wires and a second reference voltage (Vref2), and amplify or integrate a voltage difference between a voltage sensed through an (n+1)th RX wire (RXLn+1) adjacent to the nth RX wire (RXLn) and a first reference voltage (Vref1) different from the second reference voltage (Vref2). A display device is also disclosed.
