A backlight assembly includes a light generating unit, a receiving member, an optical member, and a frame member. The receiving member includes a receiving part receiving the light generating unit, a supporting part extending from the receiving part, and a protrusion portion protruded from the supporting part. The optical member is guided to a predetermined position on the supporting part by the protrusion portion, and diffuses the light provided from the light generating unit. The frame member includes a fixing part coupled with the supporting part and protruded from a surface of the frame member facing the supporting part. The fixing part prevents the optical member from moving in a direction substantially parallel to an upper surface of the supporting part.
