Abstract:
1. A manufacturing method of a pixel define layer of a light-emitting display backplane, wherein, said light-emitting display backplane, comprises a substrate and a pixel define layer provided on said substrate, and said method comprises: step 1: sequentially forming a first photosensitive resin layer, a first transparent define layer, a second transparent define layer and a second photosensitive resin layer on said substrate; step 2: providing a mask above said second photosensitive resin layer, wherein said mask has a pattern corresponding to respective pixels step 3: performing exposure, so that both said second photosensitive resin layer and said first photosensitive resin layer below said second photosensitive resin layer are exposed; step 4: removing resin from regions in said second photosensitive resin layer which correspond to respective pixels, so as to uncover the second define layer; step 5: performing etching, so as to form openings corresponding to respective pixels, in both the uncovered second define layer and said first define layer below the second define layer, wherein, during etching, etch rate at which said second define layer is etched is smaller than etch rate at which said first define layer is etched, so that the openings in said second define layer are smaller than those in said first define layer.
