A display device is provided with a display area and a frame area on a flexible substrate. The display area includes a transistor and a light-emitting element, and the frame area surrounds the display area. The display device includes: an upper inorganic insulating film, a first upper metal layer, a first resin layer, a protective layer, a second upper metal layer, a second resin layer, and a third resin layer provided in a stated order above a semiconductor layer of a transistor. In a display area, the protective layer covering a whole upper face of the first resin layer comes into contact with an upper wire included in the second upper metal layer.
