  • Publication number: 20230232665
    Abstract: A light-emitting display device can include a plurality of first electrodes over a substrate; a bank to overlap an area between the first electrodes and an edge of each of the first electrodes; a bank recess in the bank at the area between the first electrodes; a hard mask pattern to partially overlap the bank recess and to abut an upper part of the bank; an organic layer on the first electrodes and the bank, the organic layer being discontinuous between an upper part of the hard mask layer pattern and the bank recess; and a second electrode. Also, the bank can include a bank lower portion having a first height under the bank recess, a bank body portion around the bank recess, the bank body portion having an acute taper with respect to the substrate, and a bank overlap portion to overlap the plurality of first electrodes.

  • Publication number: 20160190225
    Abstract: An organic light emitting display device and a method of manufacturing the same are provided that may reduce the resistance of a second electrode and may prevent corrosion and metal migration of a pad electrode without adding a separate mask process, or while reducing the number of mask processes. In the organic light emitting display device, an auxiliary line is connected to a second electrode through an auxiliary electrode, which is provided in the same layer as a first electrode, and a pad cover electrode is configured to cover an upper surface and a side surface of a pad connection electrode so as to prevent the pad connection electrode connected to a pad from being exposed outward.
