PROBLEM TO BE SOLVED: To provide a display device in which a top face of a partition wall is formed planar or protrusive by preventing the top face of the partition wall from being deformed and recessed in a manufacture process.SOLUTION: A display device 1 comprises: a substrate 11; a first lower electrode 21 and a second lower electrode 22 which are provided while interposing a gap 25 therebetween; a first partition wall 41 that is formed from a resin material; a first organic functional layer 71 and a second organic functional layer 72; and an upper electrode 82. A bottom face 41a of the first partition wall 41 includes a first portion 41a1 and a second portion 41a2. A height from the first portion 41a1 to the second portion 41a2 of the bottom face 41a of the first partition wall 41 is 30% or less with respect to a height from the first portion 41a1 of the bottom face 41a of the first partition wall 41 to a highest point 41b2 of a top face 41b of the first partition wall 41. A width of the second portion 41a2 of the bottom face 41a of the first partition wall 41 is 20% or less with respect to a width of the first partition wall 41.SELECTED DRAWING: Figure 1 【課題】製造過程において隔壁の上面が変形して凹形状になることを防止することで、隔壁の上面が平面形状または凸形状である表示装置を提供する。【解決手段】表示装置１は、基板１１と、隙間２５を空けて設けられた第１下部電極２１および第２下部電極２２と、樹脂材料で構成された第１隔壁４１と、第１有機機能層７１および第２有機機能層７２と、上部電極８２と、を備える。第１隔壁４１の底面４１ａは、第１部分４１ａ１と、第２部分４１ａ２とを有する。第１隔壁４１の底面４１ａの第１部分４１ａ１から第２部分４１ａ２までの高さは、第１隔壁４１の底面４１ａの第１部分４１ａ１から第１隔壁４１の上面４１ｂの最高点４１ｂ２までの高さに対して、３０％以下である。第１隔壁４１の底面４１ａの第２部分４１ａ２の幅は、第１隔壁４１の幅に対して、それぞれ２０％以下である。【選択図】図１
