Patent ID: 8203666

Claim:
A method of manufacturing a backlight assembly, the method comprising: preparing a light reflective and heat-radiating sheet including a light reflective sheet layer to reflect light and a heat-radiating sheet layer including a coupling layer integrally formed with a surface of the light reflective sheet layer and, having heat-diffusing particles dispersed in the coupling layer to diffuse heat provided from an exterior, the coupling layer having adhesive layers thereon; disposing the light reflective and heat-radiating sheet so that the coupling layer is adhered to a bottom plate and sidewalls of a receiving container; and disposing a plurality of light sources on the bottom plate having the coupling layer of the light reflective and heat-radiating sheet adhered thereto, wherein preparing the light reflective and heat-radiating sheet comprises forming the heat-radiating sheet layer, wherein the heat-diffusing particles comprise at least one selected from the group consisting of boron nitride particles, silicon carbide particles, and magnesium oxide particles, and wherein forming the heat-radiating sheet layer comprises forming a first adhesive layer of the adhesive layers to adhere an upper surface of the coupling layer to a surface of the light reflective sheet layer.
