Display device
View Patent ↗A display device includes a display panel and a touch panel disposed so as to overlap with the display panel. The display panel is connected to a first flexible wiring board on which a plurality of first wirings are arranged. The touch panel is connected to a second flexible wiring board on which a plurality of second wirings are arranged. The plurality of second wirings of the second flexible wiring board are connected to second connection terminals. The plurality of first wirings of the first flexible wiring board are connected to first connection terminals. The first connection terminals and the second connection terminals are electrically connected to each other.
