Display backplane with metal layer on protrusions

A display device, comprising a backplane, wherein the backplane comprises:

• a base substrate;
• an inorganic layer provided on the base substrate, the inorganic layer comprising a plurality of protrusions protruding toward a direction away from the base substrate;
• a metal layer provided on a top of each protrusion and part of two side walls near the top of the each protrusion, the metal layer covering adjacent protrusions is disconnected;
• and
• a light-emitting layer provided on both the metal layer, and the inorganic layer between the adjacent protrusions, the light-emitting layer is disconnected at regions of the protrusions not covered by the metal layer.

A method of manufacturing a backplane, comprising:

• providing a base substrate;
• forming an inorganic layer with a plurality of protrusions protruding toward a direction away from the base substrate;
• forming a metal layer on a top of each protrusion of the inorganic layer and part of each side wall near the top of the each protrusion, the metal layer covering adjacent protrusions are disconnected;
• and
• forming a light-emitting layer on the metal layer and part of the inorganic layer not covered by the metal layer, and the light-emitting layer includes a plurality of disconnected sections disconnected from each other on corresponding disconnected portions of the metal layer.
