Abstract: A display device (50a) includes a non-display region (N) shaped in an island and provided inside a display region. The non-display region (N) includes a through hole (H) framed to penetrate the non-display region (N) along a thickness of a resin substrate (10a). In the non-display region (N), a first inorganic insulating film (11, 13, 15, 17) includes an opening (M) provided to surround the through hole (H) and penetrating the first inorganic insulating film (11, 13, 15, 17). A second inorganic insulating film (36) of a sealing film (40) is in contact with the resin substrate (10a) exposed through the opening (M) from the first inorganic insulating film (11, 13, 15, 17).

Abstract: A separation wall is provided in a frame shape along a circumferential edge of a through-hole in a non-display region, in which the through-hole is formed, defined in an island shape inside a display region. The separation wall includes a wall base portion provided in a frame shape by a part of a second interlayer insulating film and a resin layer provided in an eave shape on the wall base portion to extend to a through-hole side and a display region side. Opening portions opening upward are provided on peripheries of the wall base portion on the through-hole side and the display region side in the second interlayer insulating film.

Abstract: A display devise includes: a resin substrate; a TFT layer; and a light-emitting element. A bending portion is provided with a first resin film formed of the same material and in the same layer as those of a first flattening film, and the first resin film fills a slit. An upper face of the first resin film is provided with a plurality of first connection wiring lines formed of a third metal film, and the plurality of first connection wiring lines extend in parallel to each other in a direction intersecting the extending direction of the bending portion. The plurality of first connection wiring lines are electrically connected to a plurality of first lead-out wiring lines, respectively in a display region side of the slit, and electrically connected to a plurality of second lead-out wiring lines, respectively in a terminal portion side of the slit.

Abstract: In the display device according to the disclosure, a first bank includes a first bank lower portion in the same layer as a flattening film and a first bank upper portion in the same layer as an edge cover. A second bank includes a second bank lower portion in the same layer as the flattening film and a second bank upper portion in the same layer as the edge cover. The first bank upper portion covers an upper surface and a side surface of the first bank lower portion, the side surface being on a side close to a display region. An inclination angle of a side surface of the first bank upper portion on a side close to the display region is larger than an inclination angle of the side surface of the first bank lower portion on the side close to the display region.
