Abstract: A display device and a method of fabricating the same are provided. The display device comprises a substrate, a transistor disposed on the substrate, a via layer disposed over the transistor and including a contact hole extending to the transistor, a pixel electrode disposed on the via layer and connected to the transistor through the contact hole, a first bank layer disposed on the pixel electrode and extending in a first direction, and a second bank layer extended in a second direction crossing the first direction, a light emitting layer disposed on the pixel electrode, and a common electrode disposed on the light emitting layer, wherein the second bank layer comprises a first region that does not overlap the contact hole and a second region that overlaps the contact hole, and wherein a width of the second region is greater than a width of the first region.

Abstract: A display device includes a first substrate including an emission area and a non-emission area; a first pixel electrode positioned on the emission area of the first substrate; a first light emitting structure positioned on the first pixel electrode and including quantum dots; a pixel defining layer positioned on the non-emission area of the first substrate and positioned on the first pixel electrode; a common electrode covering the first light emitting structure and the pixel defining layer; and an encapsulation structure positioned on the common electrode and in contact with the common electrode such that the encapsulation structure overlaps the non-emission area. The encapsulation structure may include a second substrate and a hydrogen donor layer positioned between the second substrate and the common electrode. The hydrogen donor layer may overlap the emission area and may be in contact with or spaced apart from the common electrode.
