  • Patent number: 7324173
    Abstract: A side fixing frame for a liquid crystal display device is provided. The side fixing frame has a U-shaped configuration and is provided with multiple engaging elements. The engaging elements of the side fixing frame couple with corresponding counterparts of a supporting frame used in a liquid crystal display device so as to fasten the side fixing frame with the supporting frame. Because of the U-shaped configuration design of the side fixing frame, the frame can attain the desired securing strength and reduce the materials needed for producing the side fixing frame and the production cost.
