Abstract
The present invention discloses a light-emitting display backplane, a display device and a manufacturing method of a pixel define layer. A light-emitting display backplane according to the present invention comprises: a substrate and a pixel define layer provided thereon, wherein said pixel define layer comprises: a first photosensitive resin layer, a first transparent define layer and a second transparent define layer sequentially provided on said substrate from bottom to top, each of the first photosensitive resin layer, the first define layer and the second define layer is provided with openings corresponding to respective pixels, and the openings in said second define layer are smaller than those in both said first define layer and said first photosensitive resin layer, so as to form luminescent material filling regions which are wider at bottom and narrower at top.
