An LCD backlight having an extremely simple structure has been developed by utilizing a flat discharge volume with insulated electrodes. A 5.6-in. diagonal discharge volume is a mere open space in which Hg and Ar are admitted. The thickness of the volume can be varied from device to device between 1 and 3 mm. Luminance uniformity was measured to be 93% without using a diffusion sheet. Luminance can be dimmed down to 2 % of the peak value by extending the pulse period.
