Claim 0:
1. An organic light emitting diode (OLED) display, comprising:
a substrate;
a plurality of pixels including a plurality of light emitting layers between a plurality of lower electrodes and an upper electrode on the substrate, wherein the plurality of light emitting layers configured to emit a first color light;
an encapsulation layer on the upper electrode, the thin film encapsulation layer including a first inorganic layer, a second inorganic layer, and an organic layer;
a pixel defining layer on the substrate, the pixel defining layer partially exposing the lower electrodes;
a conversion layer configured to receive the first color light from the plurality of light emitting layers and convert the first color light to a light having a different color, the conversion layer comprising a quantum dots layer disposed on the encapsulation layer and a color filter layer disposed on the quantum dots layer,
wherein the first inorganic layer has a first refractive index (n1) and a first thickness,
wherein the second inorganic layer having has a second refractive index (n2) different from the first refractive index (n1) and a second thickness different from the first thickness; and
wherein the quantum dots layer comprise:
a plurality of areas disposed respectively corresponding to a plurality of sub-pixels, and
a first black matrix disposed between the plurality of areas.
