Abstract
An organic light emitting diode display includes: a substrate including a plurality of sub-pixels that each include an emission area and a non-emission area; a thin film transistor in the non-emission area; a passivation layer on the thin film transistor, the passivation layer including a surface that has random nano-patterns; a first overcoat layer on the passivation layer, the first overcoat layer including a surface having a plurality of micro lenses and the first overcoat layer having a first refractive index; a second overcoat layer on the first overcoat layer, the second overcoat layer including a flat surface and a second refractive index that is greater than the first refractive index of the first overcoat layer; and a light emitting diode on the second overcoat layer in the emission area.
