LCD screen illumination is provided by a neon tube formed to fit closely adjacent the screen. A tube formed to fit around the periphery of the screen shielded from the viewer's eyes can be utilized to front light the screen. A serpentine shaped tube can be placed adjacent the back of the screen to back light the screen. The tube can be formed to have a size coextensive with the screen configuration and can have a light diffuser between the tube and the screen to provide uniform illumination. The tube can provide any desired color, an adjustable high maximum surface brightness, high electrical efficiency and a narrow profile.
