A first metal layer provided on a resin substrate layer, a flattening film provided on the first metal layer, a second metal layer and a plurality of organic EL elements provided on the flattening film, and a sealing film covering the plurality of organic EL elements are provided. An organic layer provided in the sealing film includes a circumferential end edge positioned in a frame region. A slit overlapping the circumferential end edge of the organic layer is formed in an outer side of the flattening film. The first metal layer and the second metal layer are in contact with each other inside the slit. An opening is formed in a metal layer of the first metal layer and the second metal layer, the opening exposing an interlayer insulating film from the metal layer of the first metal layer and the second metal layer at a position at which the organic layer and the slit overlap each other.
