Abstract
Provided is a touch-panel-equipped display device that can improve the touch sensing accuracy, without decreases in the display quality, and a method for producing the same. A touch-panel-equipped display device includes an active matrix substrate 1. The active matrix substrate 1 includes a plurality of pixel electrodes 31; a plurality of counter electrodes 21 forming capacitors between the same and the pixel electrodes 31; a plurality of touch detection lines 22; a first insulating layer 461; and a second insulating layer 462. The touch detection lines 22 are connected with any of the counter electrodes 21, and supply a driving signal for touch detection to the counter electrodes 21 connected therewith. Between each pixel electrode 31 and the corresponding one of the counter electrodes 21, the second insulating layer 462 is arranged. Further, on each touch detection line 22, the first insulating layer 461 is arranged, the second insulating layer 462 is arranged on the first insulating layer 461, and each counter electrode 21 is arranged on the second insulating layer 462.
