  • Patent number: 8203666
    Abstract: In a method of manufacturing a backlight assembly, a light reflective and heat-radiating sheet including a light reflective sheet layer to reflect light and a heat-radiating sheet layer are prepared. The heat-radiating sheet layer includes a coupling layer integrally formed with a surface of the light reflective sheet layer and heat-diffusing particles are dispersed in the coupling layer to diffuse heat provided from the exterior. The light reflective and heat-radiating sheet is disposed so that the coupling layer is adhered to a bottom plate of a receiving container. Thus, impurities may be prevented and/or reduced, and assembling efficiency may be improved.
