Claims

[Scope of Claim for Utility Model Registration] 1. A small fluorescent lamp for liquid crystal lighting, a reflector that reflects the light of the small fluorescent lamp toward the back of the liquid crystal element, and a lighting circuit that is installed inside the small fluorescent lamp and the reflector. The reflector includes an outer box having an opening on the surface for illuminating the liquid crystal element, and a light diffusing plate covering the opening, and the reflecting plate is made of plastic with a mirror finish on its inner surface, and has both ends. A side plate is attached to the side plate, and the side plate has a notch groove into which a small fluorescent lamp is inserted, a power feeding tongue holder that protrudes outward from the side plate, and a tip side elastic part that is fixed to the holder. A power feeding tongue disposed diagonally across the notch groove and contacting the cap at the end of the small fluorescent lamp to bias it in the opening direction of the notch groove; A backlight device for a liquid crystal display, characterized in that it has a protrusion that prevents a compact fluorescent lamp from jumping out of a cutout groove. 2. A rib is protruded from the inner surface of the light diffusing plate, and the small fluorescent lamp is pushed in against the biasing force of the power feeding tongue by the rib, and the small fluorescent lamp is held in a fixed position close to the reflecting plate. A backlight device for a liquid crystal display according to claim 1, characterized in that:
