Display device

A display device includes: a substrate; a first sub-pixel electrode disposed over the substrate; a metal bank layer overlapping the first sub-pixel electrode; an inorganic bank layer disposed on the first sub-pixel electrode and disposed below the metal bank layer; and an auxiliary electrode overlapping the metal bank layer in the non-sub-pixel region, in which a bottom surface of the inorganic bank layer is in contact with the auxiliary electrode through the first contact hole. 一种显示装置包括：基板；第一子像素电极，设置在基板上方；金属堤层，与第一子像素电极重叠；无机堤层，设置在第一子像素电极上并且设置在金属堤层下方；以及辅助电极，在非子像素区域中与金属堤层重叠，其中，无机堤层的底表面通过第一接触孔与辅助电极接触。
