An organic EL display (1) has a bend (B) where a slit (81) is bored in a base coat film (23), gate insulating film (27), first interlayer insulating film (31) and second interlayer insulating film (35). The bend is provided with a filler layer (83) filling the slit and covering both edges of the slit. The filler layer has a protrusion (85) overlapping each edge in the width direction of the slit. A routed wire (7) routed from the display region (D) and then routed over the filler layer to reach a terminal section (T) extends over the protrusion.

A light-emitting element includes: a first electrode; a second electrode disposed opposite the first electrode; a light-emitting layer disposed between the first electrode and the second electrode and containing quantum dots; and a carrier transport layer disposed between the first electrode and a surface of the light-emitting layer on a second electrode side, including a plurality of protrusions extending toward the second electrode side, and containing a carrier transport material, wherein at least parts of the plurality of protrusions of the carrier transport layer and at least parts of a plurality of gaps between the plurality of protrusions are covered by the quantum dots.

A deposition mask includes a metal plate including first and second surfaces located opposite each other, through holes bored through the metal plate from the first surface to the second surface, and a flat region located between two through holes adjacent to each other in a case where the deposition mask is seen from the second surface side. The through holes are arrayed in a staggered arrangement in first and second directions in planar view. The flat region includes first and second flat regions located at first and second sides, respectively, of a first center line. The first center line passes through center points of two through holes adjacent to each other in the first direction. The first and second flat regions include portions in which dimensions of the first and second flat regions in the first direction increase away from the first center line, respectively.
