Abstract: An organic EL display device has a picture-frame region provided with: dam walls extending along an outer periphery of a display region to block an organic sealing layer; and a second lead wire running from toward the display region, crossing the dam walls, and extending out of the picture-frame region. The picture-frame region includes a spacer wall extending along the dam wall and provided to an outer periphery of a portion, of the dam wall, intersecting at least with the second lead wire. The spacer wall has an upper portion provided with a plurality of protruding portions at intervals along the spacer wall. The second lead wire extends to cross a portion of, the spacer wall, away from the protruding portions.
