A liquid crystal display device which includes a liquid crystal display panel, a metal shield casing covering a periphery of the liquid crystal display panel, a plurality of fluorescent lamps arranged below the liquid crystal panel, a back light support supporting the plurality of fluorescent lamps, and a lower casing fixed to the metal shield casing. The back light support is fixed in the lower casing and comprises a plurality of slits, wherein one end of the plurality of fluorescent lamps is disposed with respect to a respective one of the plurality of slits.

A liquid crystal display device includes a liquid crystal display panel and a metal shield casing which covers a periphery of the liquid crystal display panel. The metal shield casing has a plurality of fixing pawls and a plurality of fixing hooks.

A liquid crystal display device including a liquid crystal display panel, a first driver circuit substrate, a second driver unit substrate and a flexible connector. The first driver circuit substrate provides electrical connection for at least one driver chip for the liquid crystal display panel with the first driver circuit being disposed at a peripheral portion of the liquid crystal display panel. The second driver circuit substrate has at least a connector to be connected with an external circuit with the second driver circuit substrate being disposed in superposed relation to at least a portion of the first driver circuit substrate. The flexible connector electrically connects at least a part of the first driver circuit substrate to at least a part of the second driver substrate.
