To provide a display device with higher moisture permeation preventing performance, in which a component is disposed inside a display area.SOLUTION: A display device according to the present invention includes a first penetration hole 10H, an array of a plurality of pixels disposed in a display area surrounding the first penetration hole and separated from each other with the first penetration hole held therebetween, a first layer 240 disposed in an intermediate area between the first penetration hole and the display area and including a first hole or a recess, and a second layer 250 existing on the first layer and including a second hole overlapping with the first hole or the recess. The second layer includes a pair of chips further extending from an inner side surface of the first layer that defines the first hole or the recess to a center of the second hole. Each of the pixels includes a light-emitting diode including a pixel electrode 221, a counter electrode 223, and an intermediate layer 222 between the pixel electrode and the counter electrode. At least one organic layer in the intermediate layer is blocked using the pair of chips as a center.SELECTED DRAWING: Figure 8 【課題】表示領域の内側にコンポーネントが配置される透湿防止性能を向上させた表示装置を提供する。【解決手段】本発明の表示装置は、第１貫通孔１０Ｈと、第１貫通孔を取り囲む表示領域に配置され、第１貫通孔を挟んでそれぞれ離隔された画素を含む複数の画素のアレイと、第１貫通孔と表示領域との間の中間領域に配置され、第１ホール又はリセスを含む第１層２４０と、第１層上に位置し、第１ホール又はリセスに重畳する第２ホールを含む第２層２５０と、を備え、第２層は、第１ホール又はリセスを定義する第１層の内側面よりも第２ホールの中心に向かって更に延びる一対のチップを含み、複数の画素のそれぞれは、画素電極２２１、対向電極２２３、及び画素電極と対向電極との間の中間層２２２を含む発光ダイオードを含み、中間層の少なくとも一層の有機物層は、一対のチップを中心として断絶される。【選択図】図８
