Zusammenfassung:	To provide a display device capable of easily and reliably bonding a light-emitting element and a drive substrate for driving the light-emitting element.SOLUTION: A display device 10 has a light-emitting element 11 having a light-emitting element side electrode 12, a substrate 20 having a substrate side electrode 21, and a metal layer 35 for connecting the light-emitting element side electrode 12 and the substrate side electrode 21. At least at one of an interface between the light-emitting element side electrode 12 and the metal layer 35 and an interface between the substrate side electrode 21 and the metal layer 35, an intermetallic compound is formed.SELECTED DRAWING: Figure 12 【課題】発光素子と、発光素子を駆動する駆動基板とを簡便かつ確実に接合できるディスプレイ装置を提供する。【解決手段】発光素子側電極１２を有する発光素子１１と、基板側電極２１を有する基板２０と、発光素子側電極１２と基板側電極２１とを接続する金属層３５と、を有し、発光素子側電極１２と金属層３５との界面または基板側電極２１と金属層３５との界面のうち少なくともどちらか一方の界面に金属間化合物が形成されている、ディスプレイ装置１０。【選択図】図１２
