Abstract: A bent part is prevented from being damaged by preventing displacement of a bend. A display device includes a circuit substrate having a flat part and a bent part, a light emitting element layer disposed on each of unit pixels forming an image, a circuit layer stacked on an outside surface of the bent part, a sealing layer that covers and seals the light emitting element layer, and a double-sided tape that includes a base material having a first surface and a second surface, respectively provided with a first adhesive and a second adhesive, and is bent at an inside of the bent part of the circuit substrate with the first surface being outside. The first surface sticks to the circuit substrate, and the second surface is folded back and adhered together.

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.
