1. A layered structure comprising:
a transparent substrate disposed on a surface of a photoluminescent layer comprising a pattern of a quantum dot polymer composite;
a capping layer directly disposed on an opposite surface of the photoluminescent layer, wherein the capping layer comprises at least two adjacent layers including a first layer in contact with the photoluminescent layer and comprising a first inorganic material having a first refractive index, and a second layer comprising a second inorganic material and having a second refractive index, wherein the second layer directly contacts the first layer, and the first refractive index is lower than the second refractive index, and
the capping layer has a transmittance of greater than or equal to about 90% for light having a wavelength of about 380 nanometers to about 520 nanometers; and
an overcoat disposed on the capping layer, the overcoat comprising an organic polymer,
wherein the quantum dot polymer composite comprises
a polymer matrix, and
a plurality of quantum dots in the polymer matrix,
wherein the pattern of the quantum dot polymer composite comprises a repeating section and wherein the repeating section comprises a first section configured to emit light of a first peak wavelength, and
wherein each of the first and the second inorganic material comprises a metal oxide, a metal nitride, a metal oxynitride, a metal sulfide, or a combination thereof.
