Abstract
A substrate for a surface light emitting device in which a transparent electrode, an organic thin film layer, and a cathode electrode are sequentially stacked, the substrate including: a transparent support substrate; and a highly refractive layer that is disposed between the support substrate and the transparent electrode and comprises at least one layer having a refractive index that is equal to or greater than a refractive index of the support substrate, wherein the highly refractive layer comprises a light diffusion unit that diffuses light incident from the transparent electrode and a planarized surface that contacts the transparent electrode. Accordingly, a Haze value of the highly refractive layer is set to be 5% or less, and a diameter of bubbles existing in the highly refractive layer is set to be 1/10th or less of a thickness of the highly refractive layer.
