A touch panel display device is provided with an active matrix substrate having multiple pixels corresponding to N-number colors (N is an odd number of three or more). The active matrix substrate includes multiple source lines, multiple common electrodes, and multiple signal lines connected to the respective common electrodes. The active matrix substrate includes, outside its display area, a source line driving circuit, a common electrode driving circuit that supplies a predetermined voltage signal to the signal lines, source line connection portions that connect between the source lines and the source line driving circuit, signal line connection portions that connect between the signal lines and the common electrode driving circuit, and multiple outside-area dummy lines having predetermined potential. The source line connection portions of the source lines for the pixels of at least two adjacent colors are overlapped with each other, and the source line connection portions of the source lines for the pixels of the remaining color are overlapped with the signal line connection portions or the outside-area dummy lines.
