    Abstract: An electroluminescent display device can include a substrate divided into a plurality of sub-pixels having an opening area and a non-opening area, a planarization layer disposed on the substrate, an anode disposed on the planarization layer, and a bank disposed on the anode and the planarization layer, the bank having an opening exposing a portion of the anode in the opening area. The electroluminescent display device has a light emitting unit disposed on the portion of the anode; a cathode disposed on the light emitting unit and the bank. A deposition blocking layer is disposed on the cathode in a portion of the non-opening area and the opening area, and a reflective layer disposed on the cathode in another portion of the non-opening area, in which the reflective layer does not overlap with the deposition blocking layer.

    Abstract: A display device can include a substrate in which a display area and a non-display area are disposed, a thin film transistor disposed on a the substrate that corresponds to the display area, a gate driver disposed on a portion of the substrate that corresponds to the non-display area, a protection layer disposed to cover the thin film transistor and the gate driver, a planarization layer disposed on the protection layer and including a plurality of openings exposing at least a part of the protection layer in the non-display area, an organic light emitting diode disposed on the planarization layer so as to be electrically connected to the thin film transistor in the display area, and a nano particle layer disposed on the protection layer overlapping the plurality of openings. The nano particle layer includes nano particles surface-modified with a hydrophobic functional group.
