To improve the visual field angle characteristics.SOLUTION: A display device according to one embodiment comprises: a first lower electrode, a second lower electrode and a third lower electrode; a rib which has openings respectively overlapping with the first lower electrode, the second lower electrode and the third lower electrode; a first organic layer which is arranged on the first lower electrode; a second organic layer which is arranged on the second lower electrode; a third organic layer which is arranged on the third lower electrode; and upper electrodes which are arranged on the first organic layer, the second organic layer and the third organic layer. At least one of the first lower electrode, the second lower electrode and the third lower electrode includes a flat part and a plurality of inclination parts inclined with respect to the flat part in the opening. The plurality of inclination parts is arrayed in a matrix shape in the first direction and the second direction intersecting with each other in the plan view.SELECTED DRAWING: Figure 9 【課題】視野角特性を改善する。【解決手段】一実施形態によれば、表示装置は、第１下電極、第２下電極、及び、第３下電極と、前記第１下電極、前記第２下電極、及び、前記第３下電極の各々と重なる開口を有するリブと、前記第１下電極の上に配置された第１有機層と、前記第２下電極の上に配置された第２有機層と、前記第３下電極の上に配置された第３有機層と、前記第１有機層、前記第２有機層、及び、前記第３有機層の上に配置された上電極と、を備え、前記第１下電極、前記第２下電極、及び、前記第３下電極の少なくとも１つは、前記開口において、平坦部と、前記平坦部に対して傾斜した複数の傾斜部と、を有し、前記複数の傾斜部は、平面視において互いに交差する第１方向及び第２方向にマトリクス状に配列されている。【選択図】図９
