  • Publication number: 20250212612
    Abstract: A display device includes an anode electrode on a light emission area of a substrate, a light emitting layer on the anode electrode, a first pixel defining layer on the non-light emission area of the substrate, including a first side directed toward the light emission area, a bank layer on the first pixel defining layer, including a tip more protruded toward the light emission area than the first side of the first pixel defining layer, a residual pattern that overlaps the non-light emission area and is disposed between the anode electrode and the first pixel defining layer, a cathode electrode on the light emitting layer and the bank layer, and an encapsulation layer on the cathode electrode. The first pixel defining layer and the bank layer are completely overlapped by the cathode electrode, and the entire first side of the first pixel defining layer physically contacts the cathode electrode.

  • Publication number: 20240373696
    Abstract: A display device is disclosed that includes a substrate including a main region and a sub-region, the main region includes a display area in which pixels are arranged and a first non-display area around the display area, the sub-region protrudes from one side of the main region and includes a second non-display area, a circuit layer disposed on the substrate, a light emitting element layer disposed on the circuit layer, an encapsulation layer disposed on the light emitting element layer, a sensor layer disposed on the encapsulation layer, a bank located in a boundary region which is at or near where the first non-display area meets the second non-display area, a conductive pattern disposed on at least one end of the bank and extending outward from the bank, and a wire disposed in the circuit layer and connected from the sub-region to the main region. The wire passes through a region between an edge of the substrate and the conductive pattern and is spaced apart from the conductive pattern in a plan view.
