1. an organic light-emitting display device, comprising:

  • Substrate, comprises viewing area;

    Thin-film transistor, in the display area and comprise source electrode, drain electrode and gate electrode;

    Interlayer insulating film, is formed on gate electrode;

    Electrode power-line, viewing area outside and be arranged on interlayer insulating film, at least one in electrode power-line and source electrode, drain electrode and gate electrode is formed on the same layer;

    First insulating barrier, cover film transistor, and there is the first opening portion, wherein, by the first opening portion exposed electrode power line at least partially, the first insulating barrier is passivation layer;

    Second insulating barrier, to be on the first insulating barrier and there is the second opening portion, wherein, exposed the part be in around the first opening portion of the first opening portion of the first insulating barrier and the top surface of the first insulating barrier by the second opening portion, make the second insulating barrier not with electrode supply linear contact lay and the both sides of coated electrode power line;

    To electrode, be arranged on the top of viewing area with electrode supply linear contact lay;

    Pixel electrode, in the display area and be on the second insulating barrier, makes pixel electrode be electrically connected to thin-film transistor;

    3rd insulating barrier, be on the second insulating barrier, 3rd insulating barrier has the 3rd opening portion, wherein, the first opening portion of the first insulating barrier is exposed by the 3rd opening portion, make the 3rd insulating barrier not with electrode supply linear contact lay, and expose the part of pixel electrode or whole top surface by the 3rd opening portion.
