Abstract
Disclosed is an electroluminescent display device including a substrate, a first electrode provided on the substrate, a bank configured to cover an end of the first electrode and to define an emission area, and provided with a first receiving groove, an emission layer provided on the first electrode in the emission area defined by the bank, and a light absorbing layer provided in the first receiving groove of the bank, wherein the first receiving groove is formed in the bank, and the light absorbing layer is formed in the first receiving groove so that the external light is absorbed in the light absorbing layer, to thereby prevent the color interference and Haze phenomenon between the neighboring pixels.
