摘要： 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.
