Patent ID: 10620734

Abstract:
Provided is a technique that makes it possible to reduce display defects in a touch panel integrated display device. A touch-panel-equipped display device includes an active matrix substrate that includes a plurality of pixels each of which corresponds to any one of N colors (N is a natural number equal to or greater than three). The active matrix substrate includes: a plurality of source lines; a plurality of common electrodes that are used commonly for both of image display and touch position detection; and a plurality of signal lines that are connected with the common electrodes, respectively. Outside a display area of the active matrix substrate, the active matrix substrate includes: a source line driving circuit; a common electrode driving circuit that supplies a predetermined voltage signal to the signal lines; source line connection parts 12 that connect the source lines and the source line driving circuit; and signal line connection parts 510 that connect the signal lines and the common electrode driving circuit. The source line connection parts are arranged in such a manner that N source line connection parts 121(G), 122(R), 123(B) connected with the source lines of N of the pixels corresponding to N colors, respectively, are arranged in different layers so as to overlap with one another when viewed in a plan view. The signal line connection parts 510 are arranged at positions that do not overlap with the source line connection parts 12 when viewed in a plan view.
