Abstract:
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.
