Abstract: In a display device including a flexible display panel, the risk of disconnection of a wiring due to bending is reduced. A display panel includes a display function layer including display elements and a wiring on one major surface of a base material having flexibility. The display panel includes, on the one major surface of the base material, an organic-film-covered wiring area where the surface of the wiring is covered with an organic planarization film that is an organic insulating film in direct contact with the wiring. The display panel includes, in the plane thereof, a display area where the display elements are arranged and a component mounting area that is a peripheral area located outside the display area. As the organic-film-covered wiring area, a curved area is provided in the peripheral area.

Abstract: An organic EL display device includes an organic EL element having a first light-emitting portion, a second light-emitting portion, an n-type charge-generation layer, and a p-type charge-generation layer. The first light-emitting portion has a first light-emitting layer and a hole-injection layer. The first light-emitting layer is formed between an anode and a cathode. The hole-injection layer is made of amorphous carbon and in contact with the anode. The second light-emitting portion has a second light-emitting layer, which is formed between the first light-emitting portion and the cathode. The n-type charge-generation layer is formed between the first and second light-emitting portions. The n-type charge-generation layer is in contact with the first light-emitting portion. The p-type charge-generation layer is made of amorphous carbon and formed between the n-type charge-generation layer and the second light-emitting portion. The p-type charge-generation layer is in contact with the second light-emitting portion.
