Abstract
An electroluminescent display device includes a substrate including first, second, and third sub-pixel regions; an interlayer insulating layer and a passivation layer each separately disposed at the first, second, and third sub-pixel regions on the substrate; a reflective electrode disposed on the passivation layer of each of the first, second, and third sub-pixel regions; first, second, and third dielectric layers disposed corresponding to the first, second, and third sub-pixel regions, respectively, on the reflective electrode; a first electrode disposed on each of the first, second, and third dielectric layers; an insulating pattern covering an edge of the first electrode; a light-emitting layer disposed on the first electrode and the insulating pattern and substantially all over the substrate including the first, second, and third sub-pixel regions; and a second electrode disposed on the light-emitting layer, wherein the first, second, and third dielectric layers have different thicknesses.
