ト装置。[Scope of Claim for Utility Model Registration] A small fluorescent lamp for liquid crystal lighting, a reflecting plate that reflects the light of this small fluorescent lamp toward the back side of a liquid crystal element and has side walls at both ends, together with the small fluorescent lamp and the reflecting plate. A small case comprising a main body case that houses a lighting circuit inside and has an opening on the surface for illuminating the liquid crystal element, and a light diffusing plate that covers this opening, and has vertical and horizontal grooves extending from the edge of the side wall of the reflecting plate. An L-shaped groove for inserting a fluorescent lamp is formed.
A U-shaped power supply lamp holder is placed outside this horizontal groove, and this lamp holder pinches and holds the small fluorescent lamp that has been inserted from the vertical groove and moved to the back of the horizontal groove, and the small fluorescent lamp is held along the horizontal groove. A backlight device for a liquid crystal display, characterized in that when the device is moved to a corner of an L-shaped groove, the clamping force is released.
