A method of manufacturing an organic light emitting diode display panel, including forming a lower substrate, the lower substrate including a first area and a second area; forming an organic light emitting device on the lower substrate; disposing a polymer network liquid crystal on the organic light emitting device; forming a second optical layer in the second area, the second optical layer including the polymer network liquid crystal; and varying an optical property of the polymer network liquid crystal so as to form a first optical layer in the first area. 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.
