  • LIGHT EMITTING DISPLAY DEVICE AND METHOD OF MANUFACTURING SAME
    Publication number: 20240260323
    Abstract: A light emitting display device includes a plurality of anodes spaced apart from each other on a substrate, an auxiliary electrode between adjacent anodes among the plurality of anodes, a bank exposing light emitting parts of the plurality of anodes and having a bank hole exposing a part of the auxiliary electrode, a bank protection pattern on a bank side surface surrounding the bank hole and on the bank around the bank hole, an interlayer on the light emitting parts and the bank, and a cathode connected to the auxiliary electrode within the bank hole. A connection portion between the auxiliary electrode and the cathode is provided in an active area to apply a uniform voltage to the entire display area and prevent luminance non-uniformity. By the bank protection pattern, the interlayer is prevented from being damaged due to outgassing from an exposure of the bank.
