Claim 13:
14. 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 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 quantum dots layer disposed on the thin film encapsulation layer, the quantum dots layer comprising a plurality of areas disposed respectively corresponding to a plurality of sub-pixels, and a first black matrix disposed between the plurality of areas; and
a color filter layer disposed on the quantum dots layer,
wherein the first inorganic layer has a first refractive index (n1),
wherein the second inorganic layer has a second refractive index (n2) different from the first refractive index (n1); and
wherein the plurality of areas comprises:
a first area corresponding to a red sub-pixel and having a plurality of red quantum dots;
a second area corresponding to a green sub-pixel and having a plurality of green quantum dots; and
a third area corresponding to a blue sub-pixel, and

wherein the first black matrix is disposed between the first, second, and third areas.
