Abstract: The present disclosure relates to a top-emissive organic light-emitting diode display. The organic light-emitting diode comprises a substrate, an auxiliary cathode, a passivation film, a planarization film, an under-cut opening, a connecting terminal, an under-area, a bank, an organic emission layer, and a cathode. The auxiliary cathode is placed on the substrate. The connecting terminal makes contact with the top surface of the one end exposed through the under-cut opening and protrudes into the under-cut opening, being longer in length than the one end of the auxiliary cathode. The under-area is formed between the end of the connecting terminal and the one end of the auxiliary cathode. The cathode is stacked on the organic emission layer, makes contact with the side of the connecting terminal not covered by the organic emission layer, and extends all the way to the under-area.

Abstract: The present disclosure includes: a display panel separated into a light emitting unit, in which an organic light emitting diode is disposed, and a light transmitting unit which selectively transmits light; and a driving circuit configured to drive the display panel. The display panel includes a first substrate, a second substrate, and a liquid crystal layer. In the first substrate, the organic light emitting diode is disposed in the light emitting unit, and a first electrode is disposed in the light transmitting unit. The second substrate faces the first substrate, and a second electrode is disposed in the light transmitting unit. The liquid crystal layer is interposed between the first electrode and the second electrode, and adjusts a transmittance due to a difference between a voltage applied to the first electrode and a voltage applied to the second electrode.

Abstract: A top-emissive organic light-emitting diode display includes a substrate, an auxiliary line, an insulating film, an auxiliary cathode, a passivation film, a planarization film, an under-cut opening, an under-area, a connecting terminal, an organic emission layer, and a cathode. An under-cut opening exposes one end of the auxiliary cathode. The under-area is formed inside the under-cut opening by removing the insulating film underlying the exposed end of the auxiliary cathode. The connecting terminal on the planarization film extends to the under-cut opening and makes contact with the exposed auxiliary cathode. The organic emission layer is stacked on the surface of the auxiliary cathode, and is not applied to the under-area and exposes the side of the connecting terminal making contact with the auxiliary cathode. The cathode is stacked on the organic emission layer and makes contact with the side of the connecting terminal not covered by the organic emission layer.
