| 1. A method of fabricating an organic electroluminescence (EL) device, the method comprising:
preparing a first substrate and a second substrate, each including red (R), green (G) and blue (B) sub-pixels;
forming a switching element in each of the sub-pixels on the first substrate;
forming a color conversion portion including a red (R), green (G) and blue (B) conversion layers and a black matrix layer
interposed between the color conversion layers in each of the sub-pixels;
forming a lamination film by attaching at least two thin films on substantially an entire surface of the second substrate
including the color conversion portion;
forming a first electrode below the lamination film, the first electrode including a transparent conductive material;
forming an organic EL layer below the first electrode;
forming a second electrode in each of the sub-pixels below the organic EL layer;
connecting the first and second substrates using a conductive spacer; and
joining the first and second substrates and providing a seal pattern beneath the lamination film,
wherein the lamination film is formed of a film having a low moisture permeability and has a thickness of 30-100 nm,
wherein the lamination film is formed below the color conversion portion to shield moisture discharged from the R, G and B
color conversion layer.
