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: An image display apparatus includes a display panel displaying an image, and a switching panel operated in a two-dimensional or three-dimensional mode. A viewer perceives the image of the display panel as a two-dimensional or three-dimensional image depending on the mode of the switching panel. The switching panel may include first and second substrates facing each other, a first electrode layer provided on the first substrate, a second electrode layer provided on the second substrate, and a liquid crystal layer interposed between the first and second substrates. One of the first and second electrode layers may include first and second electrodes provided on a specific plane, and two opposite inner sides of the first and second electrodes may be configured in such a way that lines extending therefrom converge on at least one first position.

Abstract: A display apparatus including a light emitting device layer emitting a first light having a peak wavelength of 500 nm or less, a color control layer disposed on the light emitting device layer, the color control layer including an emitting element converting the first light, a color filter layer disposed on the color control layer, and an absorptive scattering element provided in or on the color control layer. The absorptive scattering element may include a light absorbing portion, in which absorptivity of a green or red light is greater than absorptivity of the first light. Accordingly, reflectance of the display apparatus to an external light may be reduced.
