  • Patent number: 10367045
    Abstract: Embodiments disclosed herein relate to an electroluminescence display device including a first electrode, a second electrode facing the first electrode, an emission layer between the first electrode and the second electrode, and a bank layer defining the emission layer. The bank layer may be disposed between the first electrode and the second electrode. The bank layer may include a first bank layer and a second bank layer. The second bank layer may include a black pigment. The first bank layer may be closer to the first electrode than the second bank layer, and the first bank layer may have a lower permittivity than the second bank layer.
    Type: Grant
