Abstract

The present invention provides an organic light-emitting diode (OLED) display panel, a manufacturing method thereof, and a display device. The OLED display panel includes a substrate, an electrode layer, a pixel defining layer, and a light shielding layer. The electrode layer is spaced at intervals on the substrate. The pixel defining layer is placed on the substrate. The pixel defining layer includes dams and a light opening between any two adjacent dams. Each dam includes a dam body and a light shielding layer. A projection of the light shielding layer projected on the substrate is larger than or equal to a projection of the dam body projected on the substrate.
