Claim 7:
8. A display device comprising:
a resin substrate having flexibility;
an inorganic insulating film disposed on the resin substrate;
a first wire disposed on the inorganic insulating film; and
a terminal section and a bend both disposed in a frame region located around a display region, the terminal section being provided for connection with an external circuit, the bend being bent, between the display region and the terminal section, around an axis extending in a first direction, the display region being provided for image display,
the inorganic insulating film having a slit extending in the first direction at the bend,
the bend being provided with a filler layer filling the slit and covering both of edges in a width direction of the slit,
the first wire including a plurality of routed wires routed, in a second direction, from the display region and then routed over the filler layer to reach the terminal section, the second direction intersecting with the first direction,
wherein the filler layer has a protrusion overlapping each of the edges in the width direction of the slit,
the plurality of routed wires extend over the protrusion,
a thickness from a surface of the resin substrate to an upper surface of the protrusion is greater than a thickness from the surface of the resin substrate to an upper surface of the inorganic insulating film that is in contact with the filler layer outside the slit,
the thickness from the surface of the resin substrate to the upper surface of the inorganic insulating film that is in contact with the filler layer outside the slit is greater than a thickness from the surface of the resin substrate to an upper surface of the filler layer located inside the slit,
the slit has a curved shape extending in the first direction while curving alternately to one side and another side in the second direction,
the protrusion has a curved shape extending along each of the edges of the slit,
the curved shape of the slit and the curved shape of the protrusion constitute a dip or a bump in the second direction at a location corresponding to each of the plurality of routed wires, and
the protrusion overlapping one of the edges of the slit adjacent to the display region and the protrusion overlapping the other of the edges of the slit adjacent to the terminal section are arranged in such a manner that the dips of the respective curved shapes in an identical direction and the bumps of the respective curved shapes in an identical direction correspond to the second direction.
