Abstract
A surface light source device includes a source body having a plurality of discharge spaces formed along a first direction, and electrodes for generating a dielectric barrier discharge in the discharge spaces formed on both end portions of an outer face of the light source body along a second direction substantially perpendicular to the first direction. The electrodes have capacitances that vary along the second direction. The capacitance for generating a visible ray varies in accordance with a lengthwise direction of the electrode so that the surface light source device may have improved luminance uniformity.
