ABSTRACT:
Disclosed is a liquid crystal display device that mitigates performance degradation problems, which result from assembling and fastening the covers of the liquid crystal display device. By incorporating a protecting unit that substantially isolates fastening screws from the inner volume between the upper and lower covers of the liquid crystal display device, impurities introduced by friction between the fastening screws and the covers are contained, preventing them from contamination driver circuitry in the liquid crystal display device. Further, the protecting unit holds the lamp wires for the backlight of the liquid crystal display device, preventing the fastening screws from contacting the lamp wires and potentially exposing the inner wire, which may lead to instability in the backlight supply voltage.
