Abstract:
1. A display, comprising: a substrate including a pixel driving circuit region and an opening region; a thin film transistor positioned on top of the pixel driving circuit region and having source/drain electrodes; an insulating layer positioned on top of the source/drain electrodes having a via hole exposing one of the source/drain electrodes and having a groove above and extending below an uppermost top surface of another of the source/drain electrodes; a pixel electrode contacting the exposed source/drain electrode within the via hole and extending directly onto a top of the insulating layer to physically contact the insulating layer and to completely encircle the via hole, the insulating layer being between the source/drain electrodes and the pixel electrode; a first photosensitive layer pattern positioned within the via hole in which the pixel electrode is arranged and exposing a portion of the pixel electrode extending onto a top of the insulating layer and physically contacting the insulating layer and adjacent to the via hole, a top surface of the first photosensitive layer being no higher than the portion of the pixel electrode extending directly onto a top of the insulating layer; a second photosensitive layer pattern filling said groove in said insulating layer; and an organic emission layer positioned on top of the exposed pixel electrode and on an edge of the pixel electrode encircling the via hole to directly contact the edge of the pixel electrode encircling the via hole, wherein an upper surface of the via hole, an upper surface of said groove and an upper surface of said second photosensitive layer pattern are all in a same plane.
