BACKLIGHT UNIT, AND LIQUID CRYSTAL DISPLAY APPARATUS INCLUDING IT

摘要

PROBLEM TO BE SOLVED: To provide a backlight unit capable of suppressing luminance irregularity as compared with a conventional one.

SOLUTION: This direct type backlight unit 2 is composed by housing, in an outer container 4, curved fluorescent lamps 6 each composed by forming electrodes at both ends of a glass bulb 32 having a folded portion 34 formed by folding a glass tube nearly at the middle part in its longitudinal direction and linear portions 36 and 38 that extend in parallel with each other from both the sides of the folded portion 34. Each curved fluorescent lamp 6 is housed in the outer container 4 in an attitude where both the electrodes (bushes 46) are disposed on the lower side and the folded portion 34 is disposed on the upper side in a state where the backlight unit 2 is used. An inverter device for supplying power for lighting to the curved fluorescent lamps 6 is disposed outside the outer container 4.
