Abstract
A display device includes a resin substrate and a thin film transistor layer. The thin film transistor layer includes a first inorganic insulating film, a second inorganic insulating film, and a lead-out wiring line. A frame region includes a bending portion provided with a slit constituted with a first slit and a second slit. Portions of the first inorganic insulating film on both sides in a width direction of the first slit constituting step portions are exposed from the second inorganic insulating film inside the second slit. The lead-out wiring line is electrically connected to the thin film transistor. The step portions are provided with a protruding portion having an island shape. The lead-out wiring line includes an opening covering perimeter edge surface of the protruding portion and exposing an upper face of the protruding portion.
