Display device

A display device is provided. The display device includes: a substrate; the via hole layer is arranged on the substrate; a first bank pattern layer, a second bank pattern layer, and a third bank pattern layer disposed on the via layer; a first electrode and a second electrode spaced apart from each other; a light emitting element disposed between the first electrode and the second electrode; and a bank layer disposed on the first bank pattern layer and the third bank pattern layer, and defining an emission region. The third bank pattern layer extends in a first direction and is spaced apart from each other, the first bank pattern layer and the second bank pattern layer extend from the third bank pattern layer in a second direction crossing the first direction, and a thickness of the first bank pattern layer is smaller than a thickness of the third bank pattern layer. 提供了一种显示装置。所述显示装置包括：基底；过孔层，设置在基底上；第一堤图案层、第二堤图案层和第三堤图案层，设置在过孔层上；第一电极和第二电极，彼此间隔开；发光元件，设置在第一电极与第二电极之间；以及堤层，设置在第一堤图案层和第三堤图案层上，并且限定发射区域。第三堤图案层在第一方向上延伸
