Document Type and Number:
WIPO Patent Application WO/2012/067002
Kind Code:
A1
Abstract:
The backlight device (40) is provided with a plurality of point light sources (80), a flexible circuit board (30) on which the light sources are arranged, a light guide plate (50), and a chassis (70) for housing the light sources, light guide plate, and the circuit board.
Housing sections (76) capable of housing the light sources are formed at positions on an inner side of the chassis so as to face the light incident surface (52) of the light guide plate when the light guide plate is housed. A plurality of first slits (34) and second slits (37) are formed respectively on the flexible circuit board. The flexible circuit board is configured so as to be deformable by the presence of the first slits and the second slits, so that the plurality of point light sources are allowed to be housed inside the housing sections while brought into close contact with the light incident surface of the light guide plate.
