Abstract
An organic light emitting diode display panel and a display device are provided. The display panel includes a display substrate and a phase functional layer disposed on the display substrate. The display substrate includes a plurality of pixel units. The phase functional layer includes a plurality of phase retardation layers. Each of the phase retardation layers is disposed corresponding to one of the pixel units. The phase retardation layer is configured to convert a linearly polarized light passing therethrough into a circularly polarized light. The display panel and the display device have good anti-reflective performance, so that a displayed image is not disturbed by external light and has high definition. Also, it is beneficial to realize a thin and light design of the display panel and display device.
