Abstract
A liquid crystal display device includes: a transmission-type liquid crystal panel; a sheet-like light source device for radiating light to a back surface of the liquid crystal panel, the sheet-like light source device including a lamp, a conducting lamp reflector, and a light-conducting plate; a circuit board connected to the liquid crystal panel for supplying a signal necessary for driving the liquid crystal panel; and a mechanism part for housing and holding all three of the liquid crystal panel, the sheet-like light source device, and the circuit board. 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.
