A backlight assembly includes a light source, a light-guiding plate and a
diffusion sheet that includes a first bead layer on a lower surface of
the diffusion sheet facing the light-guiding plate, and a second bead
layer on an upper surface of the diffusion sheet. To improve image
display quality, the hardness of the beads of the first bead layer facing
the light guide plate are equal to or less than that of the light guide
plate to prevent scratching of the light guide plate.
