The present invention provides an electronic device, a display panel, a drive backboard and a manufacturing method of the drive backboard, and relates to the technical field of display. The drive backboard of the present invention includes a substrate, a driving device layer, a planarization layer, a conductive layer, a spacer layer, a bonding layer and a black matrix. The driving device layer isdisposed on the substrate; the planarization layer is disposed on the surface, away from the substrate, of the driving device layer; the surface, away from the driving device layer, of the planarization layer is provided with a protruding portion and a recess portion; the conductive layer is disposed at the surface, away from the driving device layer, of the protruding portion, and is connected with the driving device layer; the spacer layer is disposed on the surface, away from the planarization layer, of the conductive layer; the bonding layer covers the surface, away from the conductive layer, of the spacer layer and the surface, away from the planarization layer, of the conductive layer, and is used for arranging a light emitting device; and the black matrix is disposed at the recessportion, and the protruding portion protrudes from the black matrix. The drive backboard of the present invention facilitates mounting of the light emitting device and facilitates reducing of the exhaust volume of the planarization layer.
