Abstract
An organic electro-luminance display device includes a first substrate and a second substrate; an array element on the first substrate, the array element including at least one thin film transistor (TFT) in each sub-pixel; a first electrode on the second substrate; a buffer on the first electrode including a first buffer at an outer region partitioning each sub-pixel and a second buffer at a region including a stepped portion of the first buffer, wherein a undercut structure is formed by the first and second buffers; an organic electro-luminescent layer in each sub-pixel partitioned by the second buffer; a second electrode formed on the organic electro-luminescent layer; and a conductive spacer for electrically connecting the TFT to the second electrode.
