Abstract: A display device includes: an interlayer insulating layer on a substrate; an organic EL array; a metal layer connected to the organic EL array; a covering member disposed outward of the organic EL array and inward of a peripheral region of the interlayer insulating layer; a lower inorganic sealing layer provided continuously on the organic EL array, metal layer, and covering member up to the peripheral region of the interlayer insulating layer; a resin sealing layer covering at least part of the lower inorganic sealing layer; and an upper inorganic sealing layer provided continuously on the resin sealing layer up to the peripheral region of the interlayer insulating layer. At least part of a peripheral portion of the metal layer has a tapered cross-sectional shape convex in a direction opposite to a direction toward one principal surface of the substrate, and the peripheral portion is covered by the covering member.

Abstract: A display device includes: a substrate; an interlayer insulating layer that is provided inward of a periphery of the substrate, on a side corresponding to one principal surface of the substrate, and includes a resin material; an organic EL array that is provided on the interlayer insulating layer and includes a plurality of organic EL elements; an embankment provided outward of the interlayer insulating layer and inward of the periphery of the substrate, on the side corresponding to the one principal surface; and a sealing layer provided continuously on the organic EL array, the interlayer insulating layer, and the embankment and extending up to the periphery of the substrate or a vicinity of the periphery to cover the organic EL array, the interlayer insulating layer, and the embankment. The cross-sectional shape of the embankment is convex in a direction opposite to a direction toward the one principal surface.
