Abstract:
1. An organic electroluminescence (EL) device, comprising: a first substrate and a second substrate facing each other and spaced apart by a predetermined interval; an array element divided into sub-pixels on the first substrate and including thin film transistors in the sub-pixels; a first electrode serving as an anode and disposed directly on the second substrate; an electrode separator disposed below the first electrode at a boundary region between the sub-pixels; an organic EL layer disposed on the first electrode; a second electrode serving as a cathode and patterned in each of the sub-pixels by the organic EL layer and the electrode separator and the second electrode formed on the organic EL layer; a conductive spacer electrically connecting the thin film transistors of the first substrate with the second electrode of the second substrate and the conductive spacer maintaining a cell gap between the first and second substrates; a plurality of interlayers respectively disposed between the first electrode and the electrode separator and between the first electrode and the organic EL layer and at regions corresponding to the electrode separator and the conductive spacer, each interlayer being formed in a pattern; and a plurality of light shielding portions respectively disposed between the first electrode and the second substrate and at regions corresponding to the electrode separator and the conductive spacer, each light shielding portion being formed in a rectangular shape, wherein the conductive spacer is disposed in an interval space between the first and second substrates; and wherein the interval space is filled with an inert gas ambient.
