Claim 0:
1. A display comprising:
a liquid crystal display panel; and
a lighting apparatus positioned on a rear side of the liquid crystal display panel,
wherein the lighting apparatus comprises:
light sources and a wavelength conversion member, the wavelength conversion member converting a wavelength of light emitted from the light sources, the wavelength conversion member including a wavelength conversion material region that includes quantum dots which are encapsulated in a material that prevents deterioration from moisture or oxygen;
an optical component having a light incident surface in opposition to the light sources, in which the optical component includes a light emission surface that faces the rear side of the liquid crystal display panel, the optical component is positioned such that the wavelength conversion member is between the optical component and the light source, the optical component is spaced from the wavelength conversion member to have a void therebetween, and the light emission surface has an uneven pattern;
at least one light source substrate that supports the light sources and supplies electrical power to the light sources; and
a prevention structure having one or more concave sections, the prevention structure being arranged relative to a first light source and associated first wavelength conversion member that has an associated wavelength conversion material region such that light from the first light source is prevented from being absorbed by neighboring wavelength conversion member regions, the prevention structure being positioned between the at least one light source substrate and the associated wavelength conversion member region such that there is a space between the associated wavelength conversion material region that includes quantum dots and the prevention structure, the space includes a material layer without quantum dots that forms an interface between the material layer itself and the associated wavelength conversion material region.
