Abstract: A liquid crystal display device includes a light source member and a display panel disposed on the light source member. The display panel includes a first substrate and a second substrate facing each other, a liquid crystal layer, and a color conversion layer that is disposed between the liquid crystal layer and the first substrate. The color conversion layer includes a light emitter and a low refractive body having a refractive index of about 1.0 to about 1.3. The liquid crystal display device exhibits high color reproducibility and improves external light extraction efficiency.

Abstract: A photoluminescence device for an image generating device includes a color conversion pattern, a color filter, and a low index of refraction layer. The color conversion pattern has a first refractive index and is configured to convert light transmitted from the image generating device from one wavelength to another. The color filter is configured to selectively pass light of a given range of wavelengths transmitted through the color conversion pattern. The low index of refraction layer has a second refractive index and is disposed between the color conversion pattern and the color filter. The second refractive index is lower than the first refractive index.
