An organic light emitting diode display device and oled

The present invention provides an organic light emitting diode OLED and a display device, the organic light emitting diode OLED includes a base substrate and at least one organic light emitting unit formed on the base substrate; an outer layer of the organic light emitting unit to the surface convex curved surface. The above-described embodiment, the organic light emitting unit by the outer surface of the convex curved design, can effectively reduce the light emitted from the organic light emitting unit due to the difference in refractive index caused by the total reflection phenomenon occurs during transmission, the light is confined each structural layer, interception of light can be improved, thereby improving efficiency and brightness of the light, the organic light emitting diode OLED to solve the problem of high luminance.
