  • Patent number: 7907230
    Abstract: In a first area, a projection section provided in a second rib is inserted into a hollow section provided in a first rib, and the first rib and the second rib are overlapped with each other such that the second rib is located inside the first rib. In a second area, the first rib and the second rib are overlapped with each other such that the first rib is located inside the second rib. Therefore, a front rib and a back rib prevent each other from moving in an overlapping direction. Accordingly, it is possible to fix the front rib and the back rib without using a rib which is another component, thereby making it possible to reduce the size and weight of an apparatus while increasing the size of a display screen.
