The present disclosure provides an organic light-emitting diode (OLED) display panel including: a substrate and a cover plate assembled into a cell, and a plurality of auxiliary electrodes formed on a side of the cover plate adjacent to the substrate, the substrate including: a base; a driving circuit layer; a pixel defining layer; a luminescent material layer; and a common electrode, wherein protrusions are provided on a surface of the pixel defining layer away from the driving circuit layer in at least one of the pixel defining regions, and the auxiliary electrodes and the common electrode have at least two electrical connection surfaces in each of the pixel defining regions provided with the protrusions correspondingly. The present disclosure improves connection efficiency of the auxiliary electrodes with the common electrode.
