Abstract:
1. An electroluminescent device, comprising: a substrate; an electrode; an organic layer including at least a light-emitting layer; a metal nano pattern which enables emission of polarized light, is shaped as stripes, and functions as an opposite electrode; and a soft substrate, wherein a plurality of protrusions and recesses are provided on one surface of the soft substrate, wherein the metal nano pattern is formed on the protrusions and recesses, and wherein a grating period of the metal nano pattern satisfies the relation of Formula 1 below: wherein D is a grating period of the metal nano pattern; λ is a wavelength of light emitted from the organic layer; n n θ wherein the metal nano pattern is discontinuously formed on the plurality of protrusions and recesses provided on said one surface of the soft substrate.
