An electronic device include: a first housing; a second housing; a display module including a flexible substrate, a TFT layer on the flexible substrate, a protection layer on the TFT layer, and a deformation region which deforms as a relative position between the first housing and the second housing changes; a bending portion including a first layer integral with the flexible substrate and bent, and a second layer integral with the TFT layer, bent and laminated on the first layer; a display driver IC (DDI) in the bending portion; a touch wire on the protection layer to be connected to a touch circuit; and a detection wire on the protection layer in the deformation region and having an electrical value changeable by physical damage to the protection layer. The detection wire extends from the protection layer to the second layer so as to be electrically connected to the DDI.
