ABSTRACT:
In a method of fabricating organic light emitting diode display, a planarization layer is annealed, cured, provided with an ashing treatment, and surface-treated to reduce roughness of the planarization layer. Therefore, it is possible to improve reduce problems such as a decrease in reflectivity and variation of color coordinates of the organic light emitting diode display due to the roughness of the planarization layer.
