Abstract
An organic light-emitting diode (OLED) display panel and a display device are provided. The OLED display panel includes first pixel units and second pixel units that are arranged symmetrically-mirrored to each other. A longitudinal direction of pixel electrode of each pixel unit is parallel to a longitudinal direction of the OLED display panel. Blue sub-pixels of each pixel unit are individually arranged in a row, and red sub-pixels and green sub-pixels are arranged together in another row, so as to alleviate technical problems where a pixel arrangement of traditional hybrid arrangement OLED panels restricts printing method.
