A backlight assembly includes a receiving container, a reflecting member, a light source, and a diffusion plate. The receiving container includes a bottom plate and a sidewall upwardly protruded from sides of the bottom plate. The sidewall has at least one recess. The reflecting member includes a reflecting part and a fixing part extended from end portions of the reflecting part to be inserted into the at least one recess. The light source is disposed above the reflecting member to generate light. The diffusion plate is disposed above the light source to diffuse the light. As a result, the manufacturing process for fabricating the reflecting member may be simplified and a size of the backlight assembly may be decreased.
