Abstract: The organic light emitting display panel includes a first electrode formed on a substrate, an organic light emitting layer formed on the first electrode, a second electrode formed on the organic light emitting layer, a front sealing layer formed on the second electrode, wherein the front sealing layer is formed by alternately laminating an inorganic barrier layer and an organic barrier layer at least once, and at least one capping layer formed between the lowest layer closest to the second electrode among a plurality of thin films of the front sealing layer and the second electrode and having a higher index of refraction than an index of refraction of the lowest layer.
