BACKLIGHT DEVICE AND DISPLAY DEVICE

摘要

A backlight device (3) comprising cold cathode fluorescent tubes (discharge tubes) (20a-20h), CCFL driving circuits (driving circuits) (T) for lighting up the respective cold cathode fluorescent tubes (20a-20h) and a reflective sheet (reflective layer) (19) for reflecting lights from the cold cathode fluorescent tubes (20a-20h) into a given direction, wherein the reflective sheet (19) is provided with a first reflective section (19a) of a non-conductive member in a portion spanning from the CCFL driving circuits (T) in the longitudinal direction of the cold cathode fluorescent tubes (20a-20h) to a given distance, and a second reflective section (19b) of a conductive member in a portion beyond the given distance.
