Abstract
Disclosed herein is an electroluminescent display device. The electroluminescent display device includes: a substrate; a plurality of anodes disposed on the substrate; a bank disposed over the substrate and the plurality of anodes, the bank comprising a plurality of openings each exposing a part of the respective anodes, and one or more holes formed between the openings; a plurality of emission layers on each of the anodes; and a plurality of cathodes on each of the emission layers. It is possible to suppress the color mixing occurring when light emitted from a electroluminescent element is reflected to another emission area for representing a different color rather than its emission area.
