    Abstract: The display device includes a connection pattern and a dummy pattern spaced apart from each other on a substrate; a via layer on the substrate; a pixel electrode on the via layer and electrically connected to the connection pattern; a light emitting layer on the pixel electrode; a control layer on the light emitting layer; and a common electrode on the control layer. The dummy pattern may include a first dummy pattern and a second dummy pattern disposed on the first dummy pattern. The first dummy pattern may include a first layer, a second layer, and a third layer each of which is made of a conductive material and is sequentially stacked. The second dummy pattern may include an organic pattern including a first portion and a second portion having different areas in a plan view.

    Abstract: A display device includes a pixel electrode, a pixel defining layer including an opening extending to a portion of the pixel electrode, a first auxiliary electrode on the portion of the pixel electrode to which the opening extends, a second auxiliary electrode on the first auxiliary electrode, an intermediate layer on the pixel defining layer and the second auxiliary electrode, and a common electrode on the intermediate layer. A side surface of the first auxiliary electrode is positioned inward of a side surface of the second auxiliary electrode within the opening of the pixel defining layer to form an undercut shape. A hole injection layer of the intermediate layer includes a first portion on a side surface of the pixel defining layer defining the opening of the pixel defining layer, and a second portion disconnected from the first portion and on the second auxiliary electrode.

    Abstract: A display device includes a thin film transistor disposed on a base substrate, an insulation layer covering the thin film transistor, an organic light-emitting diode disposed on the insulation layer, a bus electrode and an organic fluoride pattern. The organic light-emitting diode includes a first electrode electrically connected to the thin film transistor, an organic light-emitting layer disposed on the first electrode, and a second electrode disposed on the organic light-emitting layer. The bus electrode is disposed on the second electrode. The organic fluoride pattern is disposed adjacent to the bus electrode.

    Abstract: In a method and apparatus for manufacturing a donor substrate, a pattern layer which exposes a surface of a substrate is arranged on the substrate, and an organic material is deposited on the exposed surface of the substrate. The pattern layer includes a film pattern that defines a plurality of first openings and a photoresist pattern that is positioned on the film pattern and defines second openings, which correspond to the first openings, respectively, a minimum width of the second openings being smaller than that of the first openings.
