ABSTRACT:
An organic electro luminescence device includes: a display region and a non-display region defined in first and second substrates, sub-pixels defined in the display region; an array element including at least one TFT in the display region of the first substrate in each sub-pixel; a first electrode in an inner surface of the second substrate; a buffer in a predetermined region to partition an emission region of each sub-pixel on the first electrode, and an electrode separator on the buffer; an insulating layer in the emission region of each sub-pixel, and a spacer formed on the insulating layer; an organic electro luminescent layer in the emission region of each sub-pixel, the emission region including the insulating layer and the spacer; and a second electrode on the second substrate where the organic electro luminescent layer is formed.
