To provide a display device with high reliability.SOLUTION: A display device according to an embodiment comprises: a substrate 10 including a first region A1 which has a display region, a second region A2 which has a mounting region and a third region A3 which is located between the first region A1 and the second region A2; a first inorganic insulation layer 11 provided on the substrate 10 in the first region A1 and the second region A2; wiring WL formed on the first inorganic insulation layer 11 so as to extend over the first region A1, the second region A2 and the third region A3; and a second inorganic insulation layer 171 provided on the wiring WL. The second inorganic insulation layer 171 extends over a region overlapping the first inorganic insulation layer 11 at least.SELECTED DRAWING: Figure 5 【課題】信頼性の高い表示装置を提供する。【解決手段】本実施形態に係る表示装置は、表示領域を有する第１領域Ａ１と、実装領域を有する第２領域Ａ２と、前記第１領域Ａ１と前記第２領域Ａ２との間に位置する第３領域Ａ３と、を有する基板１０と、前記第１領域Ａ１及び前記第２領域Ａ２において前記基板１０の上に設けられた第１無機絶縁層１１と、前記第１無機絶縁層１１の上に形成され、前記第１領域Ａ１、前記第２領域Ａ２、及び前記第３領域Ａ３に亘って延出した配線ＷＬと、前記配線ＷＬの上に設けられた第２無機絶縁層１７１と、を備え、前記第２無機絶縁層１７１は、少なくとも前記第１無機絶縁層１１と重畳する領域に延在している。【選択図】図５
