Abstract
An organic light-emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes a substrate, a thin-film transistor device layer, a light-emitting device, a passivation layer, a planarization layer, a level-raised layer, a protruding platform, an auxiliary electrode, and an undercut channel. The protruding platform is disposed directly above the level-raised layer. The auxiliary electrode includes a contact portion and a step portion, and the step portion is located at a vertical level higher than a vertical level of the contact portion. An orthographic projection of the undercut channel on the substrate and an orthographic projection of the level-raised layer on the substrate are spaced apart from each other.
