Abstract
An backlight assembly is provided. The backlight assembly includes a substrate, a light guide plate, a plurality of adhesive tapes, and guide grooves. The substrate includes conductive patterns supplying power to a light source device, and the light guide plate is disposed to form the same plane as that of the light source device. The plurality of adhesive tapes are attached at predetermined intervals in a region where the substrate and the light guide plate overlap each other. The guide grooves are formed in a region where the adhesive tapes are attached.
