Abstract: A manufacturing method of an OLED display panel is provided. At least one of a electroluminescent material layer and a second electrode layer is formed such that a thickness of the second electrode layer in a light emitting region of the OLED display panel is less than that of the second electrode layer in a non-light emitting region of the OLED display panel. The method includes applying charges of a first conductivity type to a layer structure located below a to-be-formed layer and in the light emitting region, applying charges of the first conductivity type to a material of the to-be-formed layer, and applying the material of the to-be-formed layer having the charges of the first conductivity type to the layer structure to form the to-be-formed layer. An OLED display panel manufactured by the above method and an electronic device are further provided.
