Patent ID: 7542108

Claim:
A liquid crystal display device comprising: a liquid crystal display element and a direct-type backlight unit illuminating the liquid crystal display element from lower side, wherein the direct-type backlight unit comprises a concaved lower frame corresponding to a full area of the liquid crystal display element, a reflection plate arranged into the concaved lower frame, at least three cold cathode fluorescent lamps which are spaced evenly over and fixed to the lower frame, a diffusion plate which is arranged above and covers a full length of each of the cold cathode fluorescent lamps to controls the distribution of light from the cold cathode fluorescent lamps, a right mold covering only right side edges of the cold cathode fluorescent lamps, a left mold covering only left side edges of the cold cathode fluorescent lamps, and a spacer penetrating through the reflection plate, each of the right mold and the left mold comprises a body substantially defined by an inclined surface which inclines to the diffusion plate and located directly above only one end section of each of the cold cathode fluorescent lamps, an upper plane surface which is parallel to the diffusion plate and connects with a upper edge of the inclined surface, respectively, and the diffusion plate is supported by the spacer, the plane surface of the right mold and the plane surface of the left mold, and the diffusion plate is spaced at a predetermined distance from the cold cathode fluorescent lamps only by the spacer made of hard resin, the right mold and the left mold made of resin.
