An organic light emitting diode display panel including an upper substrate, an organic light emitting device facing the upper substrate and emitting a light to the upper substrate, and a light extraction layer disposed between the upper substrate and the organic light emitting device, including first and second optical layers each having a polymer network liquid crystal and having different optical properties, and exiting the light to the outside of the upper substrate. The optical property of the polymer network liquid crystal in the first optical layer differs from the optical property of the polymer network liquid crystal in the second optical layer.
