A display unit (1) includes a lighting apparatus (3) having a light source (5) consisting of a fluorescent tube extending in one direction and a back chassis (4) for covering a rear side of the light source (5) and for holding both ends of the light source (5), and a display panel (2) positioned in opposition to the lighting apparatus (3), which illuminates the display panel (2). On the lighting apparatus (3), provided is an isolation chamber (20) which is arranged at the rear side behind the back chassis (4) in opposition to the end of the light source (5) and has an opening (20b) at its rear side. As a benefit of attachment of the isolation chamber (20), when vibration of the back chassis (4) which is caused by on/off switching of the light source (5) is transmitted into the isolation chamber (20), vibration is partly reflected and vibration components with each phase inverted to each other are combined to be released from the opening. As a result, any abnormal noise caused by vibration of the back chassis (4) can be reduced. The display unit (1) is available for a television receiver with a built-in liquid crystal display panel. |
