Abstract: Disclosed is a light emitting display device which may prevent or at least reduce lateral leakage current. The light emitting display device includes a substrate comprising a plurality of first to third subpixels arranged to neighbor one another, each of the first to third subpixels comprising an emission part and a non-emission part to surround the emission part; a bank at the non-emission parts; first electrodes covered with the bank and respectively at the first to third subpixels to expose the respective emission parts; a first spacer structure having an inversed tapered shape configured to surround at least one side of each of the emission parts of the first to third subpixels on the bank; a common layer structure located on the first electrodes and the first spacer structure and disconnected at an edge of the first spacer structure; and a second electrode on the common layer structure.
