An organic electroluminescence device includes an array element divided into sub-pixels and including thin film transistors formed in the sub-pixels; a color conversion portion disposed below a second substrate and including a red (R), green (G) and blue (B) conversion layer for converting white light into three primary colors of red (R), green (G) and blue (B); a first electrode disposed below the color conversion portion and including a transparent conductive material; an organic EL layer disposed below the first electrode in the sub-pixels and including a plurality of stack units each including a charge generation layer, an electrode transporting layer, a hole transporting layer and an emission layer; a second electrode patterned below the organic EL layer in the sub-pixels; and a conductive spacer electrically connecting the thin film transistors with the second electrode.
