LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device is provided which reduces the weight and cost of a backlight unit and decreases occurrence of brightness spots on the display surface of a liquid crystal display panel. The liquid crystal display device includes: a liquid crystal display panel PNL configured to have a liquid crystal layer sandwiched between a pair of transparent substrates each having a pixel-forming electrode on an inner surface thereof; a backlight BL having a cold cathode fluorescent lamp CFL emitting illumination light to the rear face of the liquid crystal display panel PNL; an optical compensation sheet OPS interposed between the liquid crystal display panel PNL and the backlight BL; frames UFL, DFL housing the liquid crystal display panel PNL and the backlight BL therein. At least single light diffusion film DFF is interposed between the optical compensation sheet OPS and the backlight BL and at least the single light diffusion film DFF is fixedly retained on at least an upper side of a casing region of the upper frame UFL by a screw SC.
