Abstract: A flexible substrate including a display area and a area to be bent, the area to be bent being provided with a wiring layer and not overlapping the display area. A first resin layer that extends along a boundary of the area to be bent and continuously surrounds the area to be bent is formed. Subsequently, a second resin layer is injected into an area surrounded by the first resin layer.

Abstract: A flexible display is bent in an intermediate region such that a first region and a second region overlap each other. A spacer is disposed inside a bend of the flexible display. The spacer includes a front-side region overlapping the first region, a back-side region overlapping the second region, and a guide region overlapping the intermediate region and regulating the bend. The spacer includes, in the front-side region, a first step and a first bottom surface recessed below the guide region. The spacer includes, in the back-side region, a second step and a second bottom surface recessed below the guide region. An interval between a second reinforcing film and a second raised surface located at the second step is larger than an interval between a first reinforcing film and a first raised surface located at the first step.
