ABSTRACT:
A light-emitting display device the same includes an insulating substrate having a thin film transistor formed thereon. The thin film transistor includes a source electrode and/or a drain electrode. A passivation layer is formed on the insulating substrate over at least a portion of the thin film transistor, and has a via hole formed therein, which electrically contacts either the source electrode or the drain electrode. A pixel electrode is formed in the via hole. A light-blocking layer is formed over an entire upper surface of the passivation layer except for an area corresponding to the pixel electrode. A planarization layer is formed on an upper surface of the light-blocking layer except for an area corresponding to the pixel electrode.
