    Abstract: A photoresist composition including a photoresist composition includes a photo-luminescence nanocomposite, a photopolymerizable monomer, a first photopolymerization initiator, a second photopolymerization initiator, a binder resin, and a solvent. The photo-luminescence nanocomposite includes a first quantum dot nanocomposite, a second quantum dot nanocomposite, or a combination thereof. The first quantum dot nanocomposite includes a first quantum dot nanoparticle and a first coating layer surrounding the first quantum dot nanoparticle, the first coating layer including a first inorganic material. The second quantum dot nanocomposite includes a second quantum dot nanoparticle and a second coating layer surrounding the second quantum dot nanoparticle, the second coating layer including a second inorganic material. The first photopolymerization initiator includes an oxime-based compound, and the second photopolymerization initiator includes an acetophenone-based compound, a thioxanthone-based compound, a benzophenone-based compound, or a combination thereof.

    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 device includes: a first substrate; a second substrate facing the first substrate; a light amount control layer between the first substrate and the second substrate; a first line disposed on the first substrate and extending in a first direction and a second line disposed on the first substrate and extending in a second direction which intersects the first direction; a light blocking member disposed on the first substrate and overlapping at least one of the first line and the second line; a plurality of color conversion layers on the second substrate in respective pixel areas; and a partition wall among the plurality of color conversion layers, corresponding to the first line and the second line. The partition wall has a width less than a width of the light blocking member.
