    Abstract: A display device includes a display panel that includes a first light emitting region and a second light emitting region, each of which emits first color. A first partition wall is disposed on the display panel, which allows the first color light to be transmitted therethrough, and which has a first opening defined therein and that corresponds to the first light emitting region. A first light conversion pattern is disposed inside the first opening and converts the first color light into second color light having different color. A reflection pattern is disposed corresponding to an outer surface of the first partition wall and a top surface of the first partition. An organic material pattern is disposed on the top surface of the first partition wall and overlaps the reflection pattern. A first color filter is disposed on the first light conversion pattern and allows the second color light to be transmitted therethrough.

    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.

    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 display panel includes: a light emitting device to generate light; a plurality of color conversion patterns including: a first color conversion pattern including first scattering particles dispersed in the first color conversion pattern and configured to scatter the light of the light emitting device; and a second color conversion pattern including second scattering particles dispersed in the second color conversion pattern and configured to scatter the light of the light emitting device; a plurality of color filters including: a first color filter overlapping the first color conversion pattern; and a second color filter overlapping the second color conversion pattern; and a single, low index of refraction layer continuously extending in the surface direction to overlap the first and the second color conversion patterns. The low index of refraction layer has a refractive index lower than refractive indexes of the first and second color conversion patterns.
