摘要： Embodiments of the present invention provide a display panel and a method for fabricating the display panel. The display panel includes an active layer, a gate, a source/drain metal layer and a first conductive layer, wherein the source/drain metal layer is stacked with the first conductive layer in the non-display area. The first conductive layer is arranged in the light-emitting area and the non-light-emitting area, and the thickness of the first conductive layer is smaller than that of the source/drain metal layer. In an embodiment of the present application, by reducing the thickness of the corresponding first conductive layer in the light-emitting area, after depositing other film layers on the thinner first conductive layer, a flat anode can be obtained, thereby enabling light-emitting film layers have the same thickness and improve the light-emitting effect of the panel.

摘要： 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.
