DISPLAY DEVICE, METHOD FOR MANUFACTURING DISPLAY DEVICE, AND PRINTED WIRING BOARD

Provided are: a display device in which the occurrence of corrosion at a connection site due to ACF between a flexible circuit board and a printed circuit board is suppressed; a method for manufacturing such a display device; and a printed circuit board used in such a display device. The display device comprises a display panel, a flexible circuit substrate and a printed circuit substrate. The flexible circuit board includes a first wire and a first insulating layer. The printed circuit board includes a plurality of second wires that have a second connection area, a second insulating layer that covers the second wires such that the second connection area is exposed, and a plurality of island conductors adjacent to the second wires across a gap. The second connection area is covered with an anisotropic conductive layer. Each of the second wires in the second connection area at least partially faces a corresponding one of the first wires in the first connection area across the anisotropic conductive layer. The
