Abstract
An LED package used as a light source in a backlight assembly for an LCD includes a substrate, a plurality of light scattering protrusions on the upper surface of the substrate, LEDs separated from each other by designated intervals and arranged in a line on the substrate, and a molding portion, for sealing the upper surface of the substrate including the LEDs, and having an upper surface including two cylindrical surface sections. Each of the cylindrical surface sections has a curvature for totally reflecting light emitted from the LEDs.
