In a method of fabricating a planar light source, a first substrate is formed at first. First electrodes approximately parallel to each other are formed on the first substrate. Sets of first dielectric patterns are formed on the first substrate. Each set of the first dielectric patterns includes at least two first striped dielectric patterns, and each of the first striped dielectric patterns covers one of the first electrodes correspondingly. The edges of the top of each first striped dielectric pattern are raised in a peak shape. A phosphor layer is formed between the first striped dielectric patterns of each set of the first dielectric patterns. A second substrate is formed. The first and second substrates are bound; meanwhile, a discharge gas is injected into the discharge space.
