    摘要： A backlight unit includes a light guide plate (LGP), one or more light-emitting devices disposed to face a side of the LGP and configured to generate light, a circuit board electrically connected to the one or more light-emitting devices, a quantum dot bar interposed between the LGP and the one or more light-emitting devices and configured to convert a wavelength of light, and a housing configured to house the one or more light-emitting devices, the circuit board and the quantum dot bar, and comprising first and second open end portions and an open side portion through which a portion of the LGP is inserted. The backlight unit further includes first and second covers covering the first and second open end portions of the housing, respectively, and coupled to the housing. The first cover and the second cover respectively include a first coupling portion and a second coupling portion which are coupled to first and second ends of the quantum dot bar, respectively.

    摘要： A backlight unit and a display device are disclosed. The backlight unit includes a substrate, light sources, a side mold, a resin layer, and an optical member. The light sources are disposed on a surface of the substrate. The side mold is fixed to the substrate and surrounds the light sources. The resin layer fills a region defined by the side mold. The optical member is disposed on the resin layer. A first height of the side mold measured from the surface of the substrate is greater than a second height of the resin layer measured from the surface of the substrate. The display device includes the backlight unit and a display panel disposed on the backlight unit. Manufacture of the unit includes forming the substrate with the light units disposed on the surface, attaching the side mold to the substrate, and forming the resin layer and the optical member.
