Abstract

The present disclosure relates to a pixel device for displays and a display apparatus including the same. According to an exemplary embodiment, the pixel device may include: a first light emitting source including a first light emitting structure formed by stacking a first-1 semiconductor layer, a first active layer, and a first-2 semiconductor layer on a first base; a second light emitting source including a second light emitting structure formed by stacking a second-1 semiconductor layer, a second active layer, and a second-2 semiconductor layer on the first light emitting source; a third light emitting source including a third light emitting structure formed by stacking a third-1 semiconductor layer, a third active layer, and a third-2 semiconductor layer on the second light emitting source; and a common electrode electrically connected in common to the first-1 semiconductor layer, the second-1 semiconductor layer, and the third-1 semiconductor layer; a first electrode electrically connected to the first-2 semiconductor layer; a second electrode electrically connected to the second-2 semiconductor layer; and a third electrode electrically connected to the third-2 semiconductor layer. The common electrode and the first electrode may be formed along a side surface of the second-1 semiconductor layer and a side surface of the third-1 semiconductor layer to form a stepped structure.
