ABSTRACT:
An organic electroluminescence (EL) device includes first and second substrates spaced apart by a predetermined interval and facing each other; an array element having thin film transistors formed in a unit of sub-pixel on an inner surface of the first substrate; a color conversion portion disposed below the second substrate and having red (R), green (G) and blue (B) conversion layers for converting blue light into three primary colors of red (R), green (G) and blue (B); a lamination film formed below the color conversion portion; a first electrode disposed below the lamination film and made of a transparent conductive material; an organic EL layer formed in the unit of sub-pixel below the first electrode; a second electrode patterned in the unit of sub-pixel below the organic EL layer; and a conductive spacer electrically connecting the thin film transistors provided in the unit of the sub-pixels with the second electrode.
