Abstract
An organic light emitting diode (OLED) display panel and a display device are provided. A retaining wall of the OLED display panel includes a substrate retaining wall layer, an inorganic retaining wall layer, and an organic retaining wall layer stacked on each other. Based on a structure of the retaining wall, a height of the retaining wall is increased, which can better block movements of organic materials and reduce a distance between the retaining wall and a display region. Meanwhile, the undercut shape between the retaining wall and the display region can also increase moving paths of the organic materials, which can further reduce the distance between the retaining wall and the display region, and can prevent cutting cracks from extending to the display region along the inorganic layer and a substrate, which can further reduce frame sizes.
