Abstract: The present invention discloses a liquid crystal display and a backframe for a liquid crystal display. The backframe is configured by interlinked linkages such that the backframe can be freezed in a fully extended position in use, or be collapsible when not in use in a way that the overall dimension of the collapsible backframe is smaller than the fully extended backframe. The backframe can be switched from a fully extended position under normal use, or a collapsible position under a transportation or storage. The collapsible position occupies less volumetric weight as compared to the fully extended position so as to reduce the volumetric weight when the backframe is in transportation and storage. As a result, the performance of the transportation and storage can be therefore increased, while the cost is reduced.
