    摘要： A backlight unit and a display device including the backlight unit are provided. A backlight unit includes a substrate, light sources disposed on one surface of the substrate, a first reflective film disposed on one surface of the substrate and including first openings, each of the first openings of the first reflective film exposing each of the light sources, and wavelength filter layers disposed above the first reflective film and disposed to correspond to the first openings, the wavelength filter layers are spaced apart from each other, and each of the wavelength filter layers covers at least one of the first openings.

    摘要： 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.

    摘要： A backlight unit includes a light source, a mold frame which accommodates the light source includes at least a first sidewall and an inclined surface protruding and sloping downward from an inner side surface of the first sidewall. A second sidewall may extend from the inclined surface in which the second sidewall is arranged substantially parallel to the first sidewall and has a space therebetween. The support member is disposed on the inclined surface of the mold frame. An optical plate may be disposed on an upper surface of the support member, and the optical plate and the inclined surface of the mold frame define an optical path in a space there between.
