Abstract
A discharge gas is injected into a plurality of discharge spaces of a surface light source device that has an aspect ratio of about 0.07 to about 0.85. The discharge gas has a pressure of about 10 torr to about 120 torr with respect to a temperature for lighting the discharge gas. The discharge gas includes an inert gas having a neon gas and an argon gas. The argon gas has an amount of about 0% to about 60% by volume with respect to the neon gas. The discharge gas may function as to optimize a light-emitting efficiency of the surface light source device so that the surface light source device may have improved luminance.
