Abstract: According to one embodiment, a flexible substrate includes flexible insulating base material, conductive lines, a support body and a coating layer. The conductive lines are provided on the insulating base material. The support body supports the insulating base material. The coating layer covers the insulating base material and the support body. The conductive lines include scanning lines and signal lines. The scanning lines extend in a first direction and are arranged side by side in a second direction intersecting the first direction. The signal lines extend in the second direction and are arranged side by side in the first direction. The support body and the coating layer have a through hole in a region enclosed by two adjacent scanning lines and two adjacent signal lines.

Abstract: According to an aspect, a touch panel includes, in sequence: a stretchable array substrate, a touch detection electrode; and a resin plate. The resin plate has: a facing surface facing the touch detection electrode; and a detection surface facing opposite to the facing surface. The facing surface or the detection surface has a recessed surface. The recessed surface is provided with a high permittivity layer having permittivity higher than permittivity of the resin plate. The touch detection electrode and the high permittivity layer overlap when viewed in a stacking direction in which the stretchable array substrate, the touch detection electrode, and the resin plate are stacked.
