Abstract:
1. A light-emitting display device, comprising: an insulating substrate having a thin film transistor formed thereon, the thin film transistor having at least one of a source electrode and a drain electrode; a passivation layer formed on the insulating substrate over at least a portion of the thin film transistor, the passivation layer having a via hole formed therein, the via hole electrically couples the drain electrode to a pixel electrode; a light-blocking layer formed over an entire upper surface of the passivation layer except for an area corresponding to the pixel electrode; and a planarization layer formed on an upper surface of the light-blocking layer except for an area thereof corresponding to the pixel electrode, wherein the planarization layer further includes a light-blocking shield formed on at least one side of the via hole and extending downward from a lower surface of the planarization layer into at least one recess formed in and extending from an upper side of the light-blocking layer to a lower side thereof, and wherein the light-blocking shield extends further downward from the lower side of the light-blocking layer into at least one recess formed in and extending from an upper side to a lower side of the passivation layer.
