Abstract: The present disclosure provides an OLED display panel, an electronic device, and a manufacturing method. The OLED display panel comprises a substrate, and a plurality of pixel regions formed on the substrate to emit light of different colors. A pixel region includes a first electrode, a light-emitting function layer, and a second electrode, configured facing away from the substrate. The second electrode is a light-emitting side electrode of the OLED display panel. Differences in transmittances at different wavelengths of the second electrode satisfy the following equations: |T(450 nm)−T(530 nm)|≤15%, |T(610 nm)−T(530 nm)|≤15%, and |T(400 nm)−T(700 nm)|≤50%, where T(Xnm) is a transmittance at a wavelength of Xnm of the second electrode.
