Abstract

A layered structure including a photoluminescent layer including a quantum dot polymer composite; a light absorption layer disposed on the photoluminescent layer, the light absorption layer including an absorptive color-filter material; and a silicon containing layer disposed between the photoluminescent layer and the light absorption layer, wherein the quantum dot polymer composite includes a first polymer matrix and a plurality of quantum dots dispersed in the first polymer matrix, and the plurality of quantum dots absorb excitation light and emits light in a longer wavelength than the wavelength of the excited light; and the absorptive color-filter material is dispersed in a second polymer matrix, and the absorptive color-filter material absorbs the excitation light that passes through the photoluminescent layer and transmits the light emitted from the plurality of quantum dots and an electronic device including the same.
