Provided is a display device in which connection defects in terminal parts can be suppressed, and a method for producing the same. An active matrix substrate 1 of a display device includes gate lines, data lines arranged so as to intersect with the gate lines, pixel electrodes, counter electrodes forming capacitors between the same and the pixel electrodes, and signal lines that are connected with the counter electrodes and supply a driving signal for touch detection. Further, the active matrix substrate 1 includes a display driving circuit that supplies a control signal to at least either the gate lines or the data lines, and a touch detection driving circuit that supplies a driving signal for touch detection. Still further, the active matrix substrate 1 includes a plurality of terminal parts Ta to which the display driving circuit and the touch detection driving circuit are connected, and the terminal parts Ta have a common layer structure.
