The present disclosure relates to an OLED display panel, including: a thin-film transistor (TFT) array substrate, wherein the TFT array substrate includes a plurality of pixel areas arranged in a matrix and a non-pixel area configured to be outside of the pixel areas, at least one pixel structure formed on the TFT array substrate, wherein each of the pixel structure corresponds to one pixel area, and an organic photovoltaic formed on the corresponding non-pixel area. The present disclosure further relates a manufacturing method of the OLED display panel, including: providing a TFT substrate defined with a plurality of pixel areas and a non-pixel area; forming at least one pixel structure on the pixel areas by adopting a first mask plate to apply a thin film deposition process; forming an organic photovoltaic on the non-pixel area by adopting a second mask plate to apply the thin film deposition process.
