Abstract
An organic light emitting diode display device includes a first substrate, a thin film transistor over the first substrate, a protection layer over the thin film transistor, a light emitting diode over the protection layer, a passivation layer over the light emitting diode, a second substrate over the passivation layer, and a plurality of polymeric nanoparticles disposed within at least one of the protection layer or the passivation layer, wherein a refractive index of the plurality of polymeric nanoparticles is different than both a refractive index of the protection layer and a refractive index of the passivation layer.
