    • A method of manufacturing a mold for producing a light guide panel and a method of manufacturing the light guide panel using the mold are presented. The mold is made by manufacturing a pattern master on which a fine pattern is formed. A side mold for forming a light-receiving surface of a light guide panel is immersed in an electrolyte containing metal ions, along with the pattern master. A voltage is applied to the electrolyte and the side mold such that the fine pattern on the pattern master is transferred to the side mold with the metal ions in the electrolyte, forming a prism pattern forming portion on the side mold. The prism pattern is formed on a light-receiving portion of the light guide panel using the side mold thus prepared. The shape accuracy and surface accuracy of the prism pattern are improved by using the presented method.

    • 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. Accordingly, the backlight assembly is constructed to prevent occurrence of assembling defects and light leakage due to movement of the optical member.
