Abstract: An organic light emitting diode display pixel, a display panel and a display device are provided. The organic light emitting diode display pixel comprises a red light emitting device, a green light emitting device and a blue light emitting device arranged side by side and disposed oblique with respect to a border of the pixel. The red light emitting device and the green light emitting device are located on both sides of the blue light emitting device, which has a length larger than those of the red one and the green one. The display pixel can prolong the service life of a display panel without reducing the total aperture ratio of pixels.
