摘要： In order to solve the problem that sufficient center brightness is not always obtained in a conventional liquid crystal TV and a liquid crystal monitor, a backlight module of the invention includes a plurality of cold cathode fluorescent lamps (CFL) and a diffusing reflector below, the distance between the respective CFLs is arranged so that a central portion is narrow and an end portion is wide, and the backlight module includes a triangular sectional projection structure on at the diffusing reflector only between the CFLs between which the distance is the widest, in the end portion. According to the invention, enhancement of the center brightness without increasing consumption power, reduction in the number of CFLs, and cost reduction accompanying it are achieved.

摘要： In a liquid crystal TV, there is provided a direct back light for increasing brightness in the vicinity of the center of a screen. Plural fluorescent tubes are used for backlight, and the respective two fluorescent tubes are paired and driven. The arrangement intervals of the respective pairs are made smallest in the vicinity of the center of the screen to increase the brightness in the vicinity of the center of the screen. The use of the paired fluorescent tubes is to alleviate a variation of the brightness in each of the fluorescent tubes.

摘要： A backlight structural body of a liquid crystal display device includes, between a back plate and a frame-like mold frame, a plurality of external electrode fluorescent lamps which is arranged in parallel to each other and a pair of side frames which includes electricity supply terminals which electrically connect electrode portions of the plurality of external electrode fluorescent lamps in parallel to each other. The side frame is constituted of a lower side frame which fixes the electricity supply terminals and an upper side frame which is assembled to the lower side frame while covering the electrode portions of the external electrode fluorescent lamps which are connected to the electricity supply terminals. The upper side frame includes eaves which project in the longitudinal direction of the external electrode fluorescent lamps in a state that the eaves individually cover the respective electrode portions of the external electrode fluorescent lamps.
