Liquid crystal display device

A liquid crystal display device, comprising:

• a liquid crystal panel;
• and
• a backlight for illuminating said liquid crystal panel, characterized in that
• when the side of said liquid crystal panel on which said backlight is placed is a rear side and the side which faces said backlight is a front side,
• said backlight has:
• a housing having a side with an opening;
• a number of fluorescent lamps in long tube form which are placed inside said housing;
• and
• a light source drive circuit with a coil which drives said number of fluorescent lamps, wherein
• said number of fluorescent lamps are placed at the bottom of a lower frame which forms said housing,
• a diffusion plate which diffuses light is placed so as to cover the side with an opening of said lower frame,
• the bottom of said lower frame has such a form that the distance between said diffusion plate and said bottom is greater in the portions of the backlight in the vicinity of the two ends of said fluorescent lamps than in the center portion of the backlight,
• said light source drive circuit is placed on the rear side of said lower frame and in such a location that the distance between said diffusion plate and the bottom of said lower frame is smaller at the bottom of said lower frame than in the portion in the vicinity of the two ends of said fluorescent lamps, and
• a metal plate is provided between the rear side of said lower frame and the coil mounted in said light source drive circuit.

A liquid crystal display device, comprising:

• a liquid crystal panel;
• and
• a backlight for illuminating said liquid crystal panel, characterized in that
• said liquid crystal display device comprises a number of structurally reinforcing frames in rod form made of a metal,
• when the side of said liquid crystal panel on which said backlight is placed is a rear side and the side which faces said backlight is a front side,
• said backlight has:
• a housing having a side with an opening;
• a number of fluorescent lamps in long tube form which are placed inside said housing;
• and
• a light source drive circuit with a coil which drives said number of fluorescent lamps, wherein
• said number of fluorescent lamps are placed in parallel at the bottom of a lower frame which forms said housing,
• the bottom of said lower frame has such a form that a recess towards the front side is provided at a predetermined location,
• said light source drive circuit is placed on the rear side of said lower frame and in a region in the recess towards the front side at the bottom of said lower frame, and
• there is a region where said structurally reinforcing frame does not make contact with said lower frame along a line in the longitudinal direction of the fluorescent lamps so as to correspond to the location of the coil in said light source drive circuit.
