An optical member and a display device including the same. The optical member includes a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.

A backlight unit includes a first light guide plate, a second light guide plate disposed over the first light guide plate, and a first wavelength conversion layer disposed between the first light guide plate and the second light guide plate.

An optical member including a light guide plate including a surface disposed on a plane defined by a first direction and a second direction crossing the first direction, a low refractive index pattern disposed on the surface of the light guide plate and including an opening for exposing the surface of the light guide plate, a wavelength conversion layer disposed on the low refractive index pattern, and a passivation layer disposed on the wavelength conversion layer and covering a side surface of the wavelength conversion layer and a side surface of the low refractive index pattern at least one side portion. The low refractive index pattern has a lower index of refraction than the light guide plate, and a ratio of an area occupied by the low refractive index pattern to an area of the surface of the light guide plate decreases in the first direction.

A backlight assembly includes a light source portion including a plurality of light sources. The light sources are configured to emit light. A wavelength conversion member is disposed on the light source portion. The wavelength conversion member is configured to convert a wavelength of light emitted from the light source portion. The wavelength conversion member includes a first substrate disposed on the light source portion, a second substrate disposed on the first substrate, and a plurality of wavelength conversion layers interposed between the first substrate and the second substrate. Each of the plurality of wavelength conversion layers correspond to a light source of the plurality of light sources.

An approach is provided for a light source module and a display device including the same. The light source module includes two first light source packages configured to emit light of a first color, one or more second light source packages disposed between the two first light source packages, and a plurality of third light source packages disposed between the two first light source packages and alternately arranged with the one or more second light source packages. The one or more second light source packages are configured to emit light of the first color and the plurality of third light source packages are configured to emit light of a second color. An intensity of light emitted from each of the one or more second light source packages is approximately twice an intensity of light emitted from each of the two first light source packages.

The present invention provides a novel fluorescent chemosensor including a naphthalene diimide-Zn(II) complex, which can efficiently recognize pyrophosphate (PPi) at pH 7.4. The fluorescent chemosensor exhibits a new kind of excimer fluorescence, which is selective for PPi in 100% aqueous solution. Further, since the naphthalene diimide-Zn(II) complex of the present invention does not couple with inorganic phosphate (Pi) or adenosine triphosphate (ATP) and has high selectivity for PPi, it can be usefully used to detect pyrophosphate (PPi), which serves to transfer signals and store energy in living organisms.
