Abstract
The present invention provides an organic light-emitting diode (OLED) display panel and a display device. The OLED display panel includes a light-emitting device layer and a color conversion layer arranged in sequence. The light-emitting device layer includes a third light-emitting device disposed in a region of a green subpixel. The color conversion layer includes a green conversion layer disposed in the region of the green subpixel. The green conversion layer is configured to convert light emitted by the third light-emitting device into green light to relieve a problem of a short display lifespan of current OLED display panels.
