The mechanism part includes at least one metal part, and the at least one metal part is fixedly attached to the lamp reflector via any one of a screw fastening member, a pinch fastening member, or a snap fastening member. The liquid crystal display device is capable of reducing display deficiencies due to electric noise and is also capable of obtaining clearer images.
