摘要:
An electroluminescent display device includes: an electroluminescent display device, including: a substrate including: a first subpixel, and a second subpixel, a respective first electrode in each of the first subpixel and the second subpixel on the substrate, a trench in a boundary between the first subpixel and the second subpixel on the substrate, an emission layer on the first electrode, and in the first subpixel, the second subpixel, and the boundary between the first subpixel and the second subpixel, at least some of the emission layer being noncontiguous in the trench, a pore below the emission layer inside the trench, an upper end of the pore being relatively higher than at least some of the emission layer, and a second electrode on the emission layer.
