Abstract: A display device includes a display panel and a flexible wiring board, an end. portion of which is joined to the display panel. The flexible wiring board includes a flexible base substrate in which a through-hole is formed in a position not overlapping the display panel of an extending portion extending from the end portion joined to the display panel in plan view, a first wiring pattern. formed. to close the through-hole on one surface of the flexible base substrate, and a first resin layer having more flexibility than the flexible base substrate and formed to fill the through-hole formed in the flexible base substrate.

Abstract: A flexible circuit board includes a base material including a first surface and a second surface opposite the first surface, the base material including a conductor layer, a first insulating film covering the first surface of the base material and formed with a first opening, a first insulating member formed inside the first opening and formed with a connection port to expose the conductor layer, the first insulating member having a thermal expansion coefficient smaller than that of the first insulating film, a second insulating film covering the second surface of the base material and formed with a second opening overlapping at least a portion of the first opening in a plan view, and a second insulating member formed inside the second opening and having a thermal expansion coefficient smaller than that of the first insulating film.
