Abstract
A display device with built-in touch detection function, the display device includes source lines, detection lines, common lines, gate lines, pixels, control elements, each applying to a corresponding pixel a voltage, a common line driving circuit including a pulse generator that sequentially drives the common lines, the pulse generator generating a first pulse signal for each of the common lines, a pulse compensator, the pulse compensator generating a second pulse signal based on the first pulse signal and the potential input from each of the common lines, the second pulse signal reducing a variation in potential at each of the common lines in response to a potential at each of the source lines, the pulse compensator outputting the second pulse signal to a corresponding common line, and a touch detector that detects a position specified by a user according to the second pulse signal.
