Abstract
A surface light source device may include a first substrate and a second substrate having a plurality of space-dividing portions to divide an inner space between the first and second substrates into a plurality of discharge regions. First and second electrodes may be formed on an outer face of the first substrate or the second substrate, and the first and second electrodes have a plurality of openings corresponding to the space-dividing portions. The openings have a first opening width along a longitudinal direction of the space-dividing portions, which is smaller than a line width of the first and second electrodes. The light source may be used in a flat panel display apparatus, such as a liquid crystal display apparatus.
