ABSTRACT:
Provided is an electroluminescent display device having a negligibly small voltage drop of a cathode, no external light reflection, and high contrast and luminance. The electroluminescent display device includes a rear substrate, a first electrode layer formed above the rear substrate, a second electrode layer formed above the first electrode layer, the second electrode layer facing the first electrode layer, a light-emitting layer interposed between the first electrode layer and the second electrode layer, the light-emitting layer having at least an emission layer, a front substrate facing the rear substrate and contacting an upper surface of the second electrode layer, and a functional thin film formed between the second electrode layer and the front substrate, the functional thin film having a conductive material at least in a portion thereof contacting the second electrode layer.
