A lighting system, comprising optical members (1) and (2), a casing having the optical members (1) and (2) and lamps (4) disposed therein, first members (1a) fitted to the optical members (1) and (2), and second members (3a) fitted to the casing and mounting the optical members (1) and (2) in the casing in association with the first members (1a), wherein the first members (1a) and the second members (3a) are installed so that a stress by the self-weight of the optical members is not applied to the optical members to the vertical upper side on the vertical lower side of a display screen at both the basic position of the lighting system and a first stop position to which the lighting system is rotated from the basic position in a display plane, whereby the unevenness of brightness resulting from the deflection of the optical members of a backlight device by the self-weight thereof can be reduced. |
